I can at least do the onboarding for the techs, but I'm also pretty much expected to do it for the people that are supposed to be my managers as they often don't know what they're supposed to be doing and they keep coming and going. Having to teach my commercial manager to read a contract was a bizarre experience.

Nobody knows what they're doing, and if they do they just keep getting responsibilites until they don't have enough time to do their jobs and burn out. I've found a fairly happy medium of not giving a shit while being overworked.
