Dh works for Royal Mail.
He is, as we speak, being told that if he doesn't do part of another round after he completes his round, then he will be suspended.
Doing this other round will take him past his finish time and he will not be paid any overtime. If he doesn't do then he will suspended for 'wilful delay of mail' according to his line manager and the manager of the mail office.
The union isn't in the office today and no one can get hold of him.
Dh cannot work past his contracted finish time as he has to be home on time, to look after the children so I can get to work on time.
Can they suspend him for not working past his contracted finish time for no extra pay? Can they force him to do this?
What should he do next, bearing in mind he can't speak to the union.
