I am asking this on behalf of a friend who may be in a bit of trouble. Heard that this is a good place for employment advice. My friend told some lies to cover up a mistake, not thinking it would be a big deal. Not a smart thing to do - she realises that now. Another work colleague was persistent in exposing that my friend lied, and managed to get some evidence. My friend has been told that the company now has no choice but to investigate her for dishonesty, but so far have not confirmed if it is serious enough to lose her job.
Is dishonesty grounds for dismissal or will it just be a warning? What normally is grounds for gross misconduct/dismissal?
