To highlight some the restrictive agreements that Bassa still operate - this is taken from another site and I hope the original poster doesn't mind. It occurred fairly recently.
Five crew rostered for a single sector European flight at the start of a 3 day tour. The flight was delayed by 3 hours and arrived at 2355Z. This meant because of post flight duties it became a night duty.
The crew were then given 30 hrs off on full allowances and position home as passengers.
To summarise 5 cabin crew, 3 days away and they only operated one 40 minute sector.
This is through no fault of the crew concerned but the silly union agreements that are stuck to rigidly.
Edited to add -
The pilots also qualified for 30 hrs off under BLRs but elected to take sufficient rest (12 hrs) and operate 3 further sectors which might otherwise be cancelled.
