Honestly I can see it. Working in male dominated workplaces for so long (I am trans but they didn’t know that) taking any kind of physical or procedural shortcut, or ask for help even if it was common practice would cause my coworkers to assume that I couldn’t do it things the regular way or make them treat me as less competent even if I had done it alone or the more physically demanding way where they could see at some point in the past.

The general assumption of guys is that women are less capable and they don’t change their minds easily. There’s a big difference between regular competence and the sort of self protective over performance of competence which is nessisary to get a lot of cis guys to actually realize their assumptions are bullshit and to stop treating women like they are precocious children.

Usually doing one big thing that shatters their preconceptions does the trick. I once, in frustration at being treated like a china doll demonstrated I could lift a 200 lbs coworker and walk the length of the warehouse with him on my back. But doing that only creates me as an “exception to the rule” and they will resume that behaviour with all of my female coworkers.

If you aren’t given a chance to prove yourself capable in one big flashy way that gets the guys to shut up it can cause all manner of disordered overwork practice as you have to constantly perform for an audience of the disbelieving in small ways and hope they figure it out that they are being assholes.
