I think the ETLs, even the ones I hate, deserve their salaries. Seeing the shit they put up with, coupled with ~12 hour days, yeah, fucking take that salary. Having said that, I wish there were higher standards in place. In my store, there are ETLs that are crucial for keeping the store alive because they think of the store as a whole. They deserve their salary, and then some. They work harder than our STL.
Then, there are a few we'd be better off without. They don't think of the store as a whole. They may do enough for their title, but they otherwise don't do much to support the store, which I don't think is the role of an ETL. In that position, you can't just come in, put your head down, and do your work, without any regard for anything else. Do they deserve their salaries? Sure. But that's it.
