Hello. in Ukraine:
Before Covid we had 6 shifts, now we have 12 "half-shifts". Working time and salary cut by 50%.
Sometimes ATCs work ALL night (11 hours on duty) without substitution (lack of stuff in case of 1/2 shift +studing/illness). And administration forbids to issue zero-rate for few hours in such cases. As they are afraid of "Eurocontrol sanctions")))
Fortunately no one fired)
