I don’t see any reason why not. Just to be clear, you’re offering benefit ENHANCEMENTS. It would be much more problematic if you were seeking to reduce their benefits, in which case you’d be running the risk of constructive dismissal and breach of contract. Just don’t get why any employee would say no to more benefits. Or am I missing something? Feel free to contact me directly if you want to follow up. glennd@bongarde.com
