I was asked to resign after taking 2 sick days off with the required jobs time off.

I called in sick to work on a Wednesday morning roughly a month after the death of my roommate of 9.5 years.I also told the job that I would not be in on the next day. I did have a doctors note and sick time accrued. The reason I called in was due to exhaustion, as my roommate had been in and out of hospitals since July and he died in December. The facility I worked at was in Human Services and I had worked there 8 years with no write ups and good reviews. I came in on Friday my for my regular shift and was told by one of my bosses that we didn't work in a widget factory and didn't have time for people taking time off. I was asked to resign on Saturday. The facility I worked in had 13 employees plus some on call employees.
