Yes, this is a classic technique used to get rid of an employee you don't like, when the employee does their job well and doesn't cause trouble, so you can't think of a reason to fire them. It's also the go-to move when you don't have hiring authority over an employee you don't like because they report to a different department. You take most of their responsibility away, make sure they don't get onto any projects, and eventually they are fired as redundant. It is office politics at its dirtiest.

I'm a pretty easy guy to get along with. There is exactly one person on the whole planet that I would definitely cross the street to avoid meeting. He tried this gambit on me, but I outlasted him with the help of other managers who knew me well. Thing is, he cratered my whole division and then pretty much everybody got laid off including me. But him first. Nyah nyah!
