Quick summary. Dh was told three weeks ago his hours would be changed. This means we cant both work. His employer knows this and is why he was allowed to fit his shifts round me six years ago. much to-ing and throwing later he has been given four weeks notice backdated a week to comply with this. What I need to know is can they do this without HR lady present? (she didnt bother to turn up) Can they backdate it ? His letters say they were proposing the change not implementing it.Surely he needs a currently dated letter. If his company has more than 100 employees surely he gets 90 days warning. Would really appreciate any replies as were struggling with this now.
