Pros
With little to no real oversight, there is lots of room for professional growth.
Kontras
The reason there was no oversight was a severe lack of competence, even within the limited domains of the various jobs. Working solely to make ones boss look good did little to fix real problems with mistakes made on clients' samples. Working to help lab members do their jobs more effectively alienated management, because they had no idea what the real problems were or how to fix them. Constantly repeating the problems and causes seemed to have no effect on any permanent management, as they didn't quite fit nicely into bullet points. That is, those that appreciated descriptions and solutions of the real issues were out the door due to overwork or stress (typically those lower on the food chain).
