I would hazard that almost all stress that white collar workers deal with is not the result of having to perform repetitive manual task, but having to deal with the politics or performance demands in their workplace.

Their boss demands unrealistic timelines, actively undermines them, their coworkers are difficult to deal with, etc. I've never met anybody that works as an SWE that is stressed out because they have to fix bugs or manually migrate DBs all the time, its nearly always the environment that is the root cause.
