DH started new job in Dec, with 6 months probation period. During 3 month review he was told he was not performing as well as he should be due to gaps in his knowledge. He was told they were effectively demoting him from management role to team member with a 5k salary reduction. He was then told they were getting rid of the manager role completely and just have three team members overseeing the department (including him).
He 100% disputes the performance review and feels he made clear at his interview that there were gaps in his knowledge and was reassured training would be provided. He requested the training several times but never happened.
Can they do this? Or is it a form of constructive dismissal?
