Pros
If going to work and sleeping is your objective, work here. If stealing things along side your forman is a good thing to you, work here. If you have no ability to troubleshoot, repair, and test equipment, work here. All you need to do is be able to hold a wrench while you sleep on the job. You'll be there for 40 years.
Cons
Metro likes your urine. ALOT. If you have a disability preventing you from dropping your pants and urinating at any given moment on demand, this job isn't for you. I think they like the smell of it. Might as well just never urinate until metro passes you a cup . Because if you can't, then you will have your livelyhood taken from you. If you sometimes are late, like as in 00:00:01 late, you won't make it. Do this a few times. You will have your livelyhood taken from you.
