I've been diagnosed with golfer's elbow so using a mouse and keyboard is pretty painful. My job requires a lot of daily data entry but with the other chaos that goes on, I've left the data entry part of the job for the next shift. It's only a matter of time before my manager catches wind of this and decides to fuck with me (things like a write up, unfavorable schedule change, etc.) I do have a medical diagnosis but I'm not sure if I should talk to my manager first or take it directly to HR. Also what can I expect from the company once the accommodation request is official?
