Weird how it's advertised as a P/T job but it has a F/T feeling. I see this job as a stepping stone until you find something better. They seem hire just anyone as long as they have their security credentials and no arrests (your 10-year background is checked before getting an airport ID).
If you're expecting a straight 8-hour shift (actual F/T), it's rare unless you have back to back flights. Depending on what your post is, a typical shift is 2-4 hours for 1 flight. If you have multiple flights a day, expect a gap of a few hours in between flights, resulting in long stays at the airport unless you live in the area and don't mind commuting. No, you don't get paid for sitting around unless you're on a post and the flight is delayed. Be happy for those long breaks because you'll have more than enough to time to eat, take care of business and maybe rest your eyes.
Uniform isn't a typical faux police officer uniform. It looks like something you would wear if you're going to a private school. Supervisors and Agents wear the same thing. Don't expect to get it the same day you're hired or after training either. I was hired in July and started in September (airport IDs take forever to get done). It's almost December and I still don't have the company uniform. When I ask about it, they don't seem to know.
High turnover does exist, people either get fired (mostly for petty offenses) or they quit because they found better jobs.
The airport environment itself is great. You see different people daily! Expect passengers to stop you and ask questions. It helps if you know another language besides English too. If you don't know the answer, just direct them to someone who actually knows (ie, airline agents).
