According to RTE Six One Aer Lingus is to make 1000 cabin staff redundant with the state picking up 60% of the redundancy cost. AL then proposes to rehire some of them on poorer terms. Clearly these are not legitimate redundancies but a means to dump staff the company doesn't want.
Spurious redundancies to circumvent normal firing procedures would surely be considered unfair dismissal. The state should not be subsidising such abuse.
