My DH has been working for a company since September. Last week they told him that they were letting him go due to having too many manager level staff, they admitted that this was because two managers who had previously left the company were coming back. There was no issue with his work at all.
We assumed he had no comeback with this as he has only been there a few months, but another member of staff who was let go at the same time has contacted a union and they have said she has a case (different circumstances) and so doe DH. I'm not convinced, but if we could get some extra financial compensation out of them it would help while he looks for something else.
