It’s so rude that they wait until end of day/end of week. I’ve seen my boss do it multiple times, and it’s just like… If you know at 9am, then fire them at 9am. Don’t make them work one whole shift, undoubtedly worrying about this end-of-day meeting, before confirming they were right to be worried and firing them.

Edit: sorry, just to add - I’m sure you’re not being fired! Totally forgot that I was replying to this particular comment!
