Sorry to hear you’re going through this. I had similar thing happen to me a while ago. Same industry, I was a sys-admin at an MSP contracted to a specific client.
Got in a car accident, hit-and-run by another driver. Luckily I was not seriously injured, but my car was in the shop for 5 weeks. My spouse and I only had 1 car then, so I had no way to get onsite easily. Public transport sucks where we live, the fastest bus route to my client was an hour and 20 minutes. It used to take me 15-20 minutes to drive in the car.
I requested to work remote until my car was back from the shop, (my insurance didn’t include a rental at the time.) My MSP responded, “it’s not our problem that you got in a car accident, figure out your transportation.” They wouldn’t even compromise and let me work remote for 2-3 days of the week, even though they had presented their company as being remote-work friendly.
I wish there was a tech workers union I could join, it would have been so nice to have them start kicking some ass on my behalf.
