The interesting thing is, and I work for a state government, the state put on this big horse and donkey show two years ago about how they were going to allow employees to work from home. Now, you have to consider the public’s perception of government employees working form home. What happened after the big public roll our was that it was left up to each department’s commissioner to say yea or nay to it. Mine said nope.
If it had been that simple they could have just told me I could work from home when I felt bad, my boss at that time even told me this would help me a lot. Nope.
After I got a new boss, they fired the the other one, she saw how much time I was missing and not getting paid for but knew I was having to work while at home. She went to personnel and made them give me ADA papers to get an exception. After jumping through hoops, I got an exception. I can, on a limited basis, work from home on days I feel terrible, and get paid. 90% of my work is on the computer and by phone. By not just letting me work from home per state policy they have now given me one foot out the door by having to grant me an exception.
This all started because they moved our offices from a location with plenty of parking next to the building to downtown. I have to be at work by 6:30 now to get one of the 5 handicap parking places so I only have to walk 150 yards. Not exactly ADA compliant. Before, if I didn’t sleep due to pain and got to work at 9:00, it was no big deal because I had a place to park. Now, if I am not at work by 7:00 I will have to walk near 300 yards to my building, or park 1 mile away and ride a shuttle that does not run but a few hours in the morning and evening, making it unusable to me. Neither of those options are going to happen. If I don’t sleep and get up late, I just don’t go to work now and work from home.
I have busted the states chops over the non-compliant ADA parking, but got now where. I could get a lawyer and they would have to let me park under the building where the big-wigs park, but I am sure it would cost me in the end.
We have a new governor and I make myself friendly every time I see our new commissioner, waiting for the day I drop a hint that the parking is non ADA compliant and I may have to take disability because of it. 
I guess if my number of days I work from home goes up and they get tired of it, I’ll be forced to take disability before they try and fire me. But, if they fire me for a disability, I’ll be able to retire anyway!!
