Pros

Cons
Pay is only the minimum for Part-timers and it hurts when you're being paid the minimum compared to another guard on the same site, just because he/she is a full-time employee. Especially with certain sites for which full-timers receive more than the usual pay for covering them while part-timers receive the same - min wage. Basically, whether whatever kind of site a part-time employee is covering, he/she would be still paid the min wage despite extended distance/patrolling area. The same goes for the perks and benefits.
