Management is probably not fond. On the contrary they may want to fire the person, however, as with most Union Jobs, the lazy, disrespectful, worthless employee is the most protected because they make the most noise. If any on writes them up, they cry whatever "-ism" fits the bill and most management backs off. On the other hand, the hard working, quality employees often get screwed by the union on the rare occasion they forget to turn in a leave form on time and the government not only doesn't pay them, but also punishes them for it too. I've worked in public service for 12 years and have only really needed the union once and once my supervisor realized I knew my stuff, they left me alone. Now I pretty much run my department and have to hunt for my supervisor when I do need something. My father in law was a manager for the USPS years ago and had a couple employees he could just never get rid of.
