2. 2 Overview The harmonisation process Development of model work health and safety laws Key features of the Model Work Health and Safety (WHS) Act Changes for Victoria Where to next?

3. 3 A new process and national commitment Intergovernmental Agreement for Regulatory and Operational Reform in Occupational Health and Safety (IGA) Commitment between the Commonwealth, state and territory governments on the harmonisation of work health and safety laws. States and territories are responsible for making and enforcing their own WHS laws. Although all primary work health and safety laws across Australia draw on a similar approach for regulating workplaces, there are some differences in how this is applied in OHS Acts and considerable differences in the regulations under these Acts. Nine principal jurisdictions, each with own work health and safety laws Was no compelling mechanism at national level to drive jurisdictions to harmonise work health and safety laws COAG committed through an IGA to the harmonisation of work health and safety laws in July 2008, as part of the “Seamless Economy” initiatives The IGA commits the Commonwealth, states and territories to adopt model work health and safety laws by the end of 2011. This requires each jurisdiction to enact, or otherwise give effect to, their own laws that mirror the model laws. Harmonising work health and safety laws in this way aims to provide greater certainty and protections for all workplace parties The model work health and safety laws will consist of model WHS Act, model WHS Regulations, and model Codes of Practice.

4. 4 The Intergovernmental Agreement Establishment of a new independent national agency (Safe Work Australia) to drive reform of OHS and workers’ compensation National Review into model OHS Laws Development and maintenance of model legislation, including compliance and enforcement policies All parties to complete implementation by end of 2011 Safe Work Australia is an independent statutory agency with primary responsibility to improve work health and safety (WHS) and workers’ compensation arrangements across Australia. Safe Work Australia comprises of 15 members: - an independent Chair, Mr Tom Phillips AM - nine members representing the Commonwealth and each state and territory government - two members representing the interests of workers from the Australian Council of Trade Unions (ACTU) - two members representing the interests of employers from the Australian Chamber of Commerce and Industry (ACCI) and the Australian Industry Group (Ai Group), and - the Chief Executive Officer of Safe Work Australia (non-voting member) Safe Work Australia will play a pivotal role in realising the Commonwealth Government’s commitment to work together with state and territory governments, employers and employees to achieve harmonisation of WHS laws. Safe Work Australia is located within the Commonwealth Government and established by the Safe Work Australia Act 2008. The Safe Work Australia Bill was passed in September 2009. Safe Work Australia is jointly funded by the Commonwealth, state and territory governments through an intergovernmental agreement.

5. 5 What is model legislation? A model WHS Act, supported by model WHS Regulations and Codes of Practice. Drafting of the model WHS Act and model WHS Regulations by Parliamentary Counsels’ Committee, based on instruction by Safe Work Australia. Jurisdictions can either replace their current OHS Act by enacting a new Act or amend their current OHS Act to align with the model WHS Act. Local variation only where necessary to conform to the local legislative environment.

6. 6 Key provisions of the model WHS Act  Duties of care are not defined by the nature of employment relationship – captures new and evolving work arrangements Protects all types of ‘workers’ Positive duties for officers to exercise ‘due diligence’ Duty to consult with workers and other duty holders Protection against discrimination and coercion Unions have a right to enter workplaces Significant increase in penalties The model WHS Act will extend the scope and coverage of many work health and safety laws to better capture contemporary work arrangements that go beyond the bounds of the traditional employment relationship. This includes coverage of all people who have a worker-like relationship, by replacing the outdated concept of ‘employee’ with a broad definition of ‘worker’ which includes employees, independent contractors, outworkers, apprentices, trainees and volunteers who work in employment-like settings. Duties will also be owed to visitors to the workplace (and they will have limited duties as ‘other people in the workplace’).

8. 8 Duty of a person conducting a business or undertaking (PCBU) The principal duty holder is a ‘person conducting a business or undertaking’. This includes employers, principals, head contractors and franchisees. Additional upstream duties apply to designers, manufacturers, importers and suppliers of products used in the course of work. The duty of a person conducting a business or undertaking is probably the most significant conceptual change from the majority of current Acts. PCBU replaces current duties of employer (to employees) employer conducting business or undertaking (to others) self-employed person (to others) Sub-sets/further elements of duties for PCBUs for specific activities Cause and effect approach Everyone contributing to work to have a duty of care – can be more than one in relation to specific activities Focus will be on what you must do The principal duty holder is a ‘person conducting a business or undertaking’.

9. 9 Duty of officers The model WHS Act prescribes that officers have a duty to: Have an understanding of the nature of the operations of the entity and the hazards and risks associated with those operations. Ensure appropriate resources and processes to enable identification, elimination or control of specific WHS hazards and risks, compliance with specific obligations (consultation, incident notification). Have up to date knowledge of WHS laws and compliance requirements Verify that risks and hazards are being appropriately controlled. Ensuring there is a process for receiving, considering and ensuring a timely response to information regarding incidents, identified hazards and risks. Key elements of due diligence: The right structure for the organisation – the right people in the right place Consistency with other aspects of corporate governance, as far as is this will provide for WHS governance Effective means for information flow – information and advice The right information for the organisation, at the right time Proactive as well as responsive Clear designation of responsibilities (charters, PDs etc) Accountabilities and credible verification Be actively engaged in safety and lead from the top The model WHS Act prescribes that officers have a duty to: Have an understanding of the nature of the operations of the entity and the hazards and risks associated with those operations.

10. 10 Duty of workers and others Workers Must take reasonable care for themselves and others Must comply with any reasonable instruction, policy or procedure Other persons at the workplace Duty similar to workers Definition of workers broad - to include any person who works, in any capacity, in or as part of the business or undertaking. Once again, the intention is to capture the range of work relationships and business structures within the duty framework. Volunteer means a person who is acting on a voluntary basis (irrespective of whether they receive out-of-pocket expenses) Model WHS Act specifically protects volunteers in their capacity as workers Ensures that volunteers are not discouraged from participating in community-based activities A ‘volunteer association’ (as defined) is not treated as a business or undertaking Volunteers operating as ‘officers’ have a duty of care but are immune from prosecution as ‘officers’ for a contravention of those duties Definition of workers broad - to include any person who works, in any capacity, in or as part of the business or undertaking.

11. 11 Penalties for breaches of duty of care The model WHS Act specifies penalties in dollar amounts rather than penalty units. This will ensure that penalties apply uniformly across Australia. The intention is for penalty amounts to be reviewed as part of the general review process every five years. Penalties for duties of care – criminal offences Offence based on risk and culpability rather than outcome, not requiring actual harm - Category 1 – most serious breaches, for a duty holder who recklessly endangers a person to risk of death or serious injury - Category 2 – failure to comply with a health and safety duty that exposes a person to risk of death, serious injury of illness, and - Category 3 – failure to comply with a health and safety duty . ‘Gross negligence’ removed from offences – cuts across criminal laws and manslaughter offences. Anticipated that most prosecutions will be under categories 2 and 3 Offence provisions: Offence provisions in the model WHS Act may be modified to comply with local drafting protocols that apply in the relevant jurisdiction. In practice, this means that the offence provisions in the Commonwealth, the Australian Capital Territory and the Northern Territory will designate strict liability elements. These jurisdictions are commonly referred to as ‘code’ jurisdictions as they have adopted (either wholly or in part) the model criminal code. This requires those jurisdictions to take a different approach to drafting offence provisions.The model WHS Act specifies penalties in dollar amounts rather than penalty units.

12. 12 Consultation and engagement PCBU must, so far as reasonably practicable: Consult with workers Consult, co-operate with and co-ordinate activities with other persons who have a duty in relation to the same matter Health and Safety Representatives (HSRs) for work groups Must be established on request from a worker Can direct unsafe work to cease and issue provisional improvement notices, but only if trained Health and Safety Committees Must be established within 2 months where requested by HSR, or 5 or more workers Issue resolution procedures The model WHS Act establishes comprehensive duties to consult in relation to specified work health and safety matters. It deals with consultation between duty holders as well as consultation with workers. The duty to consult is based on recognition of international evidence which demonstrates that worker input and participation improves decision-making about work health and safety matters. The duty to consult will apply to all employers regardless of the number of workers they have. The legislation departs from an emphasis on the process of consultation to provide guidance on what meaningful consultation is and when persons conducting a business should consult, as well as how persons conducting a business can consult. The model WHS Act provides choice and flexibility regarding how consultation can occur to enable a person conducting a business and their workers to adopt the consultative arrangement which they believe will ensure effective and meaningful consultation without placing too much of a burden on the business. Within the flexible framework, the model WHS Act provides for use of the traditional workplace consultative tools including Health and Safety Representatives and/or a health and safety committee. Alternative consultation procedures cannot undermine the role of Health and Safety Representatives under the model WHS Act.The model WHS Act establishes comprehensive duties to consult in relation to specified work health and safety matters.

13. 13 Right to refuse unsafe work The model WHS Act clarifies that workers have a right to cease and refuse work where they have a reasonable concern that they would be exposed to a serious risk to their health or safety.

14. 14 Anti-discrimination provisions Protection for all workers, HSRs, prospective workers and those in commercial arrangements from discrimination Protection extends to unlawful coercion or inducement Similar to Victorian provisions Criminal – ‘dominant reason’ Civil – ‘substantial reason’ Prohibition of multiple actions The model WHS Act includes broad anti-discrimination provisions that make it an offence for persons to discriminate against others who exercise work health and safety powers under the model WHS Act, and also those who carry out functions under the model WHS Act (e.g. Health and Safety Representatives and members of health and safety committees).The model WHS Act includes broad anti-discrimination provisions that make it an offence for persons to discriminate against others who exercise work health and safety powers under the model WHS Act, and also those who carry out functions under the model WHS Act (e.g. Health and Safety Representatives and members of health and safety committees).

15. 15 Role of Unions WHS entry permit holder can enter to inquire into suspected breaches, as well as to consult and advise workers subject to permit and member eligibility requirements, protections and accountability Aligned with requirements in the Fair Work Act 2009. No notice for suspected breach 24 hours notice to consult, advise or obtain documents A WHS entry permit holder must, at all times when exercising a right of entry, have his or her WHS entry permit and photographic identification available for inspection. Must also hold a Fair Work Act entry permit or the relevant state or territory industrial law entry permit. Whether a Fair Work entry permit or state or territory industrial law entry permit is required will depend on the workplace which the WHS entry permit holder is entering. For instance: - the FW Act requires that a union official must hold a Fair Work Act entry permit when entering all workplaces of constitutional corporations, all workplaces in Territories and all workplaces (with minimal exceptions) in those States that have referred their industrial relations power to the Commonwealth; - if a WHS entry permit holder was wishing to enter a State government office in many jurisdictions, they would also be required to hold a current State industrial law entry permit. Eligibility for a WHS entry permit The authorising authority may issue a WHS entry permit to an official of a union, on application, if that official: - has satisfactorily completed prescribed WHS training, and - holds, or will hold, a FW Act entry permit or the relevant state or territory industrial law entry permit. Entering a workplace to inquire into a suspected contravention of the model WHS Act: A WHS entry permit holder is not required to give prior notice when entering a workplace to inquire into a reasonably suspected contravention of the model Act. This is similar to the requirement found in the Fair Work Act 2009 (FW Act) in relation to the exercise of rights under State and Territory OHS legislation. Entry to inspect or take copies of employees records or documents not held by the PCBU: A WHS entry permit holder is required to give 24 hours notice to the PCBU and the person from whom documents or records are sought if they are entering a workplace to inspect or take copies of: - employee records that are directly relevant to a suspected contravention of the model Act, - records or documents that are directly relevant to a suspected contravention of the model Act that are not held by the PCBU. - Again, this is similar to requirements found in the FW Act. Entry to consult with and advise workers A WHS entry permit holder is required to give at least 24 hours notice to the PCBU before entering a workplace to consult on WHS matters and provide advice on those matters to relevant workers. While at a workplace to consult with and advise workers a WHS entry permit holder may warn any person of a risk to their health and safety. A WHS entry permit holder must, at all times when exercising a right of entry, have his or her WHS entry permit and photographic identification available for inspection. Must also hold a Fair Work Act entry permit or the relevant state or territory industrial law entry permit. Whether a Fair Work entry permit or state or territory industrial law entry permit is required will depend on the workplace which the WHS entry permit holder is entering. For instance: - the FW Act requires that a union official must hold a Fair Work Act entry permit when entering all workplaces of constitutional corporations, all workplaces in Territories and all workplaces (with minimal exceptions) in those States that have referred their industrial relations power to the Commonwealth; - if a WHS entry permit holder was wishing to enter a State government office in many jurisdictions, they would also be required to hold a current State industrial law entry permit.

Entering a workplace to inquire into a suspected contravention of the model WHS Act: A WHS entry permit holder is not required to give prior notice when entering a workplace to inquire into a reasonably suspected contravention of the model Act. This is similar to the requirement found in the Fair Work Act 2009 (FW Act) in relation to the exercise of rights under State and Territory OHS legislation. Entry to inspect or take copies of employees records or documents not held by the PCBU: A WHS entry permit holder is required to give 24 hours notice to the PCBU and the person from whom documents or records are sought if they are entering a workplace to inspect or take copies of: - employee records that are directly relevant to a suspected contravention of the model Act, - records or documents that are directly relevant to a suspected contravention of the model Act that are not held by the PCBU. - Again, this is similar to requirements found in the FW Act. Entry to consult with and advise workers A WHS entry permit holder is required to give at least 24 hours notice to the PCBU before entering a workplace to consult on WHS matters and provide advice on those matters to relevant workers. While at a workplace to consult with and advise workers a WHS entry permit holder may warn any person of a risk to their health and safety.

16. 16 Compliance and Enforcement Role to provide advice Regulator able to accept enforceable undertakings as an alternative to prosecution Inspectors broad powers of entry to workplaces can issue improvement, prohibition, non-disturbance and infringement notices assist in issue resolution Requirement to answer questions or provide a document Inspectors must give warning about self incrimination Review of decisions Two stage process of internal review (of inspectors decisions) and external review Graduated enforcement approachGraduated enforcement approach

17. 17 Key changes for Victoria Moving away from employment as the basis for duties, obligations and rights. New positive duty of care for officers to exercise ‘due diligence’. Broadened obligations to consult with workers and other duty holders. Only trained HSRs will have power to issue Provisional Improvement Notices or direct that unsafe work cease. Greater protection against discrimination and coercion. Enhanced powers to obtain documents and information. Many of the proposed reforms are already in place in Victoria, which means that there will be less changes in Victoria than other jurisdictions. However, significant changes in Victoria include: moving away from employment as the basis for duties, obligations and rights – to cover all kinds of worker-like relationships new positive duty of care for officers to exercise ‘due diligence’ to ensure compliance with the model WHS Act broadened obligations to consult with workers and also others who have a health and safety duty in relation to the same matter only qualified Health and Safety Representatives will have power to issue Provisional Improvement Notices or direct that unsafe work cease greater protection against discrimination and coercion, and enhanced powers to obtain documents and information.Many of the proposed reforms are already in place in Victoria, which means that there will be less changes in Victoria than other jurisdictions.

19. 19 How will harmonisation be maintained? Proposed amendments to be decided by Workplace Relations Ministers’ Council (WRMC) at the national level If WRMC agree to the amendment, then all jurisdictions must adopt the amendment in order to maintain national consistency Review every five years The IGA requires that if any jurisdiction proposes an amendment that impacts on the operation of the model work health and safety laws, the amendment must be brought to WRMC for decision at the national level. If WRMC agree to the proposed amendment, all jurisdictions must adopt the amendment in order to maintain national consistency. The model work health and safety laws are to reviewed every five years (Recommendation 232) The IGA requires that if any jurisdiction proposes an amendment that impacts on the operation of the model work health and safety laws, the amendment must be brought to WRMC for decision at the national level.

20. 20 Where to next? Safe Work Australia will give final endorsement of the amended model WHS Act at the Safe Work Australia Members meeting in April 2010. Safe Work Australia Members will be provided with an exposure draft of the model WHS Regulations for approval in September 2010. If approved, this will be provided to WRMC for endorsement in October. Safe Work Australia will be releasing an exposure draft of the model WHS Regulations, model Codes of Practice, Issues Paper and Regulation Impact Statement (if required) for public comment in late 2010 for a period of four months. This is an important opportunity for all Australians to actively participate in the development of model workplace health and safety laws.
