It is very difficult to advance in this company in spite of reliability or work ethic because of favortism. Many positions don't even involve an interview, you are just selected by the higher ups. I've worked under a supervisor that I trained as a regular gaurd and yet she was premotioned over me, and I've been looked over at other times even though I was told my hard work is appreciated and I will advance, it amounts to nothing. The current supervisor at one of the sites has been there only a year and is making the company look bad in front of the client. Sad.
