zurg,
I've yet to find a company who can get making people redundant correct. You are not alone in your frustrations. Been there before.
Good luck....find out your rights and stand up for them.
A few years ago, it took a few colleagues and myself, nine months to fight, but we got what we were entitled to in the end, including pension rights, which they tried to shaft us on. The company we worked for "downsized" and ceased to operate our part of the operation on 18 hours notice.
Good luck.
