My name isXXXXX and I'm happy to help with your question today. I need to ask you some preliminary questions to be able to help you.
Is his pay being reduced? Or will he be doing the admin job for the same money?
Admin job for same money. They have taken his phone and laptop off him as well as office keys.
OK. Bear with me for a few minutes while I draft an answer.
Thanks for your patience. If your son does not accept the demotion, even though he is on the same pay, he could leave immediately and claim constructive dismissal. He would need to show that:
If your son accepts the job on the new terms then he will not be able to claim constructive dismissal.
If he is successful in his claim for constructive dismissal your son could claim damages for wrongful dismissal e.g. breach of contract.
The point is that although he has resigned from his current position, his employer is forcing him to accept unreasonable changes to his employment without his agreement e.g. demotion.
Thank you for your help here.
