My husband was just recently dismissed from his job after almost 13 years of service while he was on parental leave. He found out because of an announcement that was made introducing the new manager at his branch - which is his role. He called his employer who said he'd been restructured. His job is still there and in fact there are to be four new like positions available in the coming weeks. He has a clean record and recently won an award for performance just prior to going on parental leave. Is this legal?
