Warned how? With a personal letter or just a vague notice to crew or was it a groupwise memo? Could it have been missed or misunderstood? I really don't know how the warning was communicated...do you?
If I recall correctly it was via a notice to crew. Pretty much as Crunchero has said.
If you need to take compassionate leave because of a death in the family or you are under huge stress because of a divorce etc then you aren’t fit for work. This was told to me by someone in flight ops. Go see your doctor and get a certificate to say you are sick and unfit for work.
