I hate working with sh*tty Devs

I used that term specifically.. No it's not about juniors, it's about those who pretend to be seniors.
In a major company project, one of us has to take a week or two to refactor that one "senior" dev work. When tested it performs poorly, when checked, it violates every SE principle and the business people are wondering why we keep seeing `refactoring User Stories/Tasks` and why we still don't have a working project yet. Yes, we will never have, that mess that `senior` dev created is almost impossible to refactor without major rework.
Now, major rework coming, we need to give something to that Senior so he doesn't feel left behind. Argue to never let him get anything in core or this company will go under...

In short, I hate working with sh*tty devs.
