Hmm, I guess maybe I am more lucky. It has happened reasonably frequently to me that someone gets an ugh-field around a task that some other person doesn’t find stressful (examples: organizing spreadsheets, calling businesses, having meetings, writing long explanatory blogposts).
But I do agree that reassignment is definitely much less frequent than just talking through whatever is aversive and usually one can find some other solution to the problem (in my experience pair-programming or pair-writing is often pretty successful here).
Maybe I need to be more heterogenous in my hiring!
I hadn’t heard of pair-writing but it sounds like it could work well in my context.
