Blatant disregard for preserving people's hearing. Most of my coworkers are of the opinion that not wearing hearing protection while operating loud tools and equipment (chainsaws, pneumatic drills etc) is not a big deal. What's worse they will often not bother to give a heads up to people working nearby that they are about to start. As a musician, and also someone with a family history of hearing loss, this kind of behavior pisses me off

Rattling ceiling tiles. I have a stick at my desk devoted to banging on ceiling tiles so they stop rattling. That sound is literally one of the most annoying things I experience.

No one else seems to care.

One place I worked had end of shift meetings every day for the transition between third and first shift. First shift was supposed to get there 15 minutes early, but hardly ever did. This was a stand-up meeting at the end of an 8 hour shift. Look assholes, I'm tired and I wanna go home.Your disrespect of my time isn't helping my attitude toward this shit-hole company. Also, apparently, they didn't need to do this for second shift, because, you know, first shift is tired and wants to leave on time. Imagine that. I ended up quitting when they tacked on extra hours for us to work at the last minute during the week of Thanksgiving, so that effectively we'd still end up working 40 hours. What's the fucking point of holidays if you're just going to make us work more hours anyway?

A lack of basic level manuals and work flows for basic job duties.

Holy shit folks, where is my picture book that lets me know how this 15 year old point of sale system out in a rural post office is supposed to do the things that I need it to do?

I deliver pIzza and all of our in-store routing software is tied to Google. It's a good GPS but it gets so much wrong. During rushes it's the job of the managers to route us on doubles or triples and I've gotten routed on badly-chosen doubles (i.e. 3 miles from each other) because Google thought the addresses were right next to each other. Sometimes it's a customer issue, like a typo on the website but most of the time it's Google being dumb.
