I can definitely relate to the last (l never earned a college degree) paragraph. Bosses, owners, partners don't want or need the grief. As it should be. You are hired to do a job. They want, and need, it done with minimal issues.
In the 23+ total years with the firm, I've seen a lot, and seen a lot of coworkers come and go.
Overselling their skills in interviews and then not being able to produce as promised, other incompetence, blaming coworkers, slacking, whining, etc., or any combination thereof.
So, basically, if your a lying, incompetent, unable to accept responsibility, whining, slacker don't even bother trying to make it in the real business world.
At least, not at our firm, anyway...!
