Re: Yes, you can
"Of course you can, even in the UK, if you use loopholes. Simply make the staff "redundant" and hire replacements with different job titles."
Nope. If the job has similar responsibilities (i.e. looks & quacks like a duck), or it was reasonably foreseeable that the staff would need to be re-hired, then that's not a "loophole", but a straightforward violation. Of course, it would require the staff to have the wherewithal, time, money, knowledge, and inclination to do something about it, which is generally unlikely.
