Legal Question in Employment Law in United Kingdom

Your question is leaving out necessary information.

If your respect towards your employer is in question, then she may ask you to clarify your position.

If she is asking what you do in your free time (I can read your question as if you were together with her husband on his two day outing), then she has no right to do so.

If it is about gossiping at work, that may be a sackable offence (malicious slander).
