Pluspunten
I really liked the job I was doing. CCTV, Access Control. The fellow techs were great to work with. Spent most of the day driving, about 1/3 of the day doing actual work.
Minpunten
Long hours. My last full week, I hit 57 hours. Not enough training, most of the stuff I did, I had to figure out on my own. Thank God for Google. If you need help or need to escalate to a higher level technician, management looks down on you. If you hire someone to work on security systems, maybe take the actual time to train on security systems. They might have you tag along with another tech to learn, but they'll schedule him for jobs you already know how to do. No real feedback on how you're doing. Can't improve if you really don't know how you're doing. You literally bleed for the company and then they suddenly make up a reason to get rid of you. Beware of supervisors that act like your friend, it's an act. He'll tell you that you're fine doing something, then later he'll fire you for it.
