Using the Internet for Surveys • Questionnaire database GTE with • obligatory questions • alerts for unlikely combinations of answers • 3-step choosers to identify • ISCO-occupation • NACE-industry • collective agreement (NL only) • multinational
Working hours measured • standard week at workplace • contractual hours • weekly working hours agreed with employer • not asked for full-timers with agreed hours contractual hrs = standard wk • usual weekly hours • not asked for full/part-timers with agreed hours and usually not working the number of agreed hours • for all others asked, if agreed hours usual hours - contractual hours = overtime • actual weekly hours • asked only as yes/no working usual hours in the past seven days • waged weekly hours • asked after questions about wage

Calculating hourly wage • hours input based on • a checked hours-measure based on contractual / usual / waged hours • gross wage divided by payment period • control for overtime • approx 40-50% of full-timers with overtime have unpaid overtime • approx 90% of part-timers with ‘overtime’ have paid ‘overtime’ • > subtract overtime allowances (if reported) from wage • control for annual bonuses received in month of survey
Atypical cases • annualised or flexible hours • measured as median of minimum / maximum hours per wk • if no data min. or max. hours per week ???? • if only annual hours available? • self-employed • only values for usual hours • piece-rate workers • exclude if piece rate is 80-100% of gross wage
Paid vacation and holidays • Normally included in wage for payment period >= 1 week (?) • no check whether this is included • Paid vacation ranges from • few days to seven weeks a year • Paid holidays ranges from • 7 to 20? days a year • How to include in the calculated hourly wages?
