For me it’s the fact that where I work the management don’t give a fuck about the staff and the fact that we got promised new equipment which we got but a week later they chained up to a rail so that only one shift can use it.
So let some steam off and talk about it.
I feel you. My first jobs were in fast food, then Walmart, then warehouse jobs after that. So even though I’m a web developer now I still have that eternal frustration with people moving too slow.
