[Cthulhu_]

This is true. Too many developers out there that think their job is to do what they're being told. It's the same type of developer that will then go to one of the Stack Exchange type of websites and complain that their boss isn't giving them time to refactor or write unit tests.

They don't give you time because they expect you to do so on your own accord. It's part of your job description. Another part of your job description is to make sure your manager is too busy managing, and doesn't have the time to micro-manage your time.

If they have enough headspace to tell you NOT to write unit tests, they aren't effective leaders.

that said, there's a difference between refactoring and rewriting a thing in a different language. At this point in my career, I'd be VERY hesitant to do the latter. The time spent in a rewrite is better spent refactoring and updating the existing codebase. It's just not as sexy on your CV.
