I'm in a pickle. My work got bought out. The new boss sends his crew in to help me do my job that I've done 99 percent by myself for 4 years. The crew is unskilled, do drugs, have bad attitudes, and need supervision to get the job done. They have no tools of their own, and depend on their supervisor for everything.
I have no say in anything these guys do, whatsoever. Their supervisor keeps giving them my jobs, which they do poorly, and needs to be redone, which everyone is ignorant of, except me. If I say anything, I get told I'm creating a problem. So now I'm a problem for speaking up about people doing my job, without any input, and telling them the quality is poor. I've spent the last 4 years fixing this nonsense so I wouldn't have to fix it again.
