Hi, I have a friend who works nights at a supermarket, he is married with 2 children and both he and his wofe work. The supermarket he works for has been bought out and he decided (when given the choice) to stay on his old contract which would give him additional pay for working sundays as his contract was to include sundays anyway. The management now have told him he has to change his hours and can no longer work sundays. They plan to employ someone else to do his sunday hours, who wont get additional payment for sunday hours. He needs to work on a sunday as that is how he arranges childcare with his wife.
Are they legally entitled to do this?
Can he do anything about it?
Thanks
