I have an employee who's mother just died. I'm going to make them use their vacation days for their grieving period.
That's so mean. Why would you do this to them?
I'm just doing it because I feel like it.
If you don't have a good reason other than you just feel like it, then you shouldn't make people use their time off to grieve. It is wrong and the person could quit leaving you without somebody you need.
Who cares... I think I'll just do it anyways.
Your lack of empathy is quite concerning and you should feel more compassion for people who are grieving. Being a cruel employer isn't beneficial to anyone and you should allow people time off when they experience such loss.
