I’ve often found in my position that it is strictly up to my direct supervisor whether or not I can work from home when sick. The fun part is, if you work from home sick, you lose however many work from home days you have a week as you stay home. So, if you work from home a day cause your sick (and it isn’t your scheduled at home day), you’ll be coming on your stay-at-home day the following week. I don’t necessarily take issue with it (seeing as how I have the privilege to work from home at all), but I feel its like they’re punishing you after you’ve already dedicated yourself to continue working while you’re sick. Then again, it’s an incentive to just call it a day off and take the PTO (provided you have it).
If it were me, my rule of thumb would be: A) Do you sound like death? B) Are you not keeping your productivity at least at 75% of the norm (I figure it’s equivalent to having a pointless meeting in the middle of your day)? C) Did you lose any limbs?
If you answer yes, you’re probably staying home and not working today.
