Discussion on question by user1582024: Is it unprofessional to simply announce your absence in case of a family death?

This is a real-life funeral and a role-play software job? If your supervisor is your academic supervisor then the context of the role-play is irrelevant here - you're absent as a student, not an employee. If your supervisor is another student trying to maintain "character" while you're experiencing real-life issues, he is way out of line.

It would be worthwhile to add a country tag as that would affect the legal ramifications and what is protected. For instance in Canada/US you do not "Ask" you simply inform and take time off (similar to illness).

This depends on the culture but unless your in a fascist regime I am pretty certain that a death is taken as a significant loss with grievance, funeral rights; etc. making a huge impact on your work performance alone. Perhaps your supervisor did not listen closely to your announcement. The places I have worked in the US seem to find a death a good reason to move to an announcement as opposed to say a dentist's appointment. Most of the places I work only require you to ask when there is a major deadline though.

I also experienced a loss recently. At our weekly sales meeting I told everyone that I'd be taking some time off for my family & the funeral. In no way did I feel it necessary to ask permission from my director. If he had pulled me aside or informed me in front of others that I should have "asked", I would have told him to shove it. In situations like this you are most likely numb, so what you do & say are often outside the limits of your normal behavior and most will forgive a faux pas.. because it's not one.

@JonathonCowley-Thom I have been the advisor in this setting. And I think it would have been immensely overstepping my assigned authority and tasks to try to teach "the world is unfair" in this way and setting. I have been the "annoyed customer" if deadlines were not met, but dragging in "real-life" like this is not in the scope of what is supposed to be taught. At all. And in any legal circumstances I have ever worked with, a student can never be forced to be anywhere, so in fact they legally do not need any permission for not participating.
