Whilst not wishing to sidetrack this debate, nor use it as a platform for criticism of "atypical employment", surely this is the opportunity EASA & the European Govts should use to put an end to zero hour contracts/bogus self employment etc.
The probability of someone , already depressive, self reporting a mental health issue , has got to be very low, if he understands that his income will thereafter be zero until he resumes flying duties again.
Turkeys don't usually vote for Xmas, and the elephant in the room that EASA et al will probably ignore is that the issue here is trying to make it less punitive for someone to seek help . . . . simples, give them the possibility to continue with their income protected (or at least a high percentage of it ) until the issue is resolved one way or another.
Inbetween zero-hour contracts & the brave new world of companies offering no (or inadequate ) loss of licence coverage, I don't see how we can realistically expect to increase self reporting.
