“…The following categorical dummies are used: employee (routine non-manual and routine service sales), professional (administrators, officials, managers in industrial establishments, large proprietors, higher-grade technicians, and supervisors of non-manual employees), civil servant, and manual worker (skilled/semi-skilled manual, farm labour) as the reference category. In addition, job authority is often related to work autonomy (Schieman et al, 2013); thus, a control was used to indicate the level of job authority the worker has: no job authority, management tasks, and extensive leadership. By controlling for these variables, we are examining the increase in income and overtime above and beyond that stemming from changes in job positions or increase in job authority.…”
