Tyrolean Airways
Airline must give part-time within 12 months unless training capacity (which is linked to number of turboprop pilots) is consumed by expansion/replacement.
60% to 85,19% range for part time. (if 85,19 sounds weird, that's 4 working days per calendar week)
60% work = 60% of full salary, etc.
All limits for working days, working time, flight time, etc. are reduced as per part-time percentage.
Overtime limits are also reduced but duty overtime up to 100% is paid without premium. After reaching 100% the normal 1,5 rate for duty overtime. (block time overtime is always linear)
Currently "reduction of working days" is the only part-time model available for pilots. I.e. you just work less days per month. Month-on/Month-off models or varying part-time over the year (e.g. more work in summer, less in winter to allow for part-time studying) could be applied for but I am not aware of any.
Cabin crew have 5 days on - 5 days off (resulting in 71% with some extra days off thrown in) and parents of children up to 7 years old may apply for fixed days off (or - as this is a legal requirement - actually anything they want as long as the company cannot prove it is impossible or impractical).
Longer blocks of duty and off time are being studied to satisfy the requirements of the large number of Tyrolean pilots who are not native Austrians.
