Try to get to know your possible manager as best you can prior to accepting the position. If you see a red flag... Trust yourself. There are MANY issues with Scantron/Secur-Serv but most are manageable with a decent manager. Otherwise there's is a high potential for disaster. Lots of turnover reflects this. Could be a decent place to with some changes and if you get lucky enough to live in an area with a manager you can work with. Workload can be stressful at times.
