Guidance please whilst I take control of my boiling blood.
A staff member presents a Doctors Note dated 20 June advising they are unfit to work from 19 June to 22 June for reasons of "Assault Left Blue Eye". Turns out that Boetie got into a fight with his girlfriend and the staff member got in the way.

4 days for a "Blue Eye"???!!! And she expects us to pay her Sick leave for the absence.
Legally I think we are probably obliged to just accept the Doctors judgement on this BUT on principle I feel I shouyldn't have to.
Particularly because it doesnt appear to have been a major incident. No fractures no eye injury of any note.

Legal guidance would be sincerely appreciated in this matter.
