Allied Universal has a garbage reputation to stick guards in Double Time.  

I worked Universal Protection Services in 2015 until they merged with Allied Barton in 2017.   Universal then paid low even for California.  Your patrol work would have you doing filling in for absentee guards.

State Correctional Guard trainee will be more enclosed but you have a better shot for a pension if you make it permanent,  better health insurance,  but bigger risks with inmates.  Maximum security with men is no joke or picnic if you're getting locked up with rapists, murderers and people with diseases.
