A Complicated Tupe Question

Our employer is in a partnership deal with the OEM, the OEM has now decided to take the work back in house, we have been told that TUPE will be enforced which I think means we either have to move to the OEM or they will have to offer redundancy. The problem with moving to the OEM is that its 500 miles away. If I didn't want to move and the OEM then refuses to offer compulsory redundancy, what can I do?

It helps if you stick to one thread so we know the background.

You need to speak to your union. Your may have a mobility clause - they are common in civil service contracts and you appear to have one (a civil service contract). In which case it is relocate or resign - no redundancy would be involved.

I am not in a mobile grade, our union won't get the opportunity to speak to the other companies HR until mid January. I thought I would ask two separate questions not to complicate the issue.

Does not being a mobile grade help us in regards to getting redundancy when the alternative is 500 miles away? or might we have to resign and go for constructive dismissal (this effects about 80 people) due to 500 miles being an unfair relocation.
