Well not me, but my husband.
His job is cleaning a pub (not self-employed), which belonged until
yesterday to a brewery, who employed him. He has worked there for 6
months. He has been told that in law he should now be employed by the
new owner (not a brewery), but this morning the new owner wouldn't let
him in or answer the door.
Can the new owner just ignore him and hope he goes away, or what? Does
he have rights, and what should we do next?

Thank you.
