Most of what I've seen is **** pay I'll agree, but there are a few that pay very well. I work some part times with a security company and get compensated anywhere from $30-45/hr for 12 hour shifts, no benefits obviously, but they require the employee be employed with a POST certified LEA.
post certified leo side gig work is completely different than a run of the mill security guard though. a post certified leo should get at least that much for side gigs. the 2 off duty that stay at the clifton CDC make 55hr last i heard when i worked there years ago.
