How many postal workers?

Not to hijack, but does it pay well?? I've seen a few openings near me and i've thought about trying to jump ship to a new career.

Pay & benefits are pretty good but.....there is almost always a but aint there?

It is not what it once was. When I started in NJ it was very laid back. Could be that every last one of us was a worker. When I transferred to Phoenix it was entirely different. Micro manged at its finest. Thanks to the number of human speed bumps it was an entirely different atmosphere.
When you first start there is no such thing as a holiday. Also no such thing as a 9-5 weekend off job. Don't get injured, either on the job or off. Used to be if you got hurt on the job you were given a limited duty job so that you would get paid. Thanks to every thing falling apart now you will be told to stay home until you can fulfill the obligations of your job. A bit of reading about the Reassessment Program , might want to search for more current info on it but you get the idea. When this happens, as long as you have an accepted claim thru Injury Comp you are supposed to get paid. The above mentioned program is what will happen if you end up out on Workman's Comp...Anyhow if you do find yourself out because of an on the job injury best of luck getting paid by OWCP, the federal workman's comp. You get hurt off the job, just stay home until you are healed.
My perception has always been that the USPS does not there best to not want you there. Look at the hiring process, takes most folks several years to get in. Depending on what craft you are in and where you are at you will be a Part Time Flexible employee, which means no guarantee of getting 40 hours, or a set schedule. When I was a PTF in NJ I was lucky to work the day shift, days off were Sunday/Friday. Worked every Friday, most Sundays. Several days I was off the clock, going to my car only to be told I had 4 more hours to go. Would get a call at 2 a.m., I was needed at 4. Other folks were lucky to get 20 hours a week.
If you are serious about wanting to work there I would suggest trying to get into maintenance. IN particular as an ET, an electronic technician. They are full time employees at hire...and pretty much always in demand. And for the most part they are left alone by management. Sure, your will get the occasional douche like Terry Cook was. But for the most part they have to deal with very little crap, compared to a mail handler (what I was) or a clerk.
Or get into the Inspection Service. But for that you will have to be flexible in where you reside. I have a buddy that did an internship with them, and has a job waiting for him pending him getting a degree....
The USPS also has it's own versions of Federal Laws. Don't bother trying to fight it, as the Justice Department is the USPS's legal side. File an EEO complaint and you will be told that if they treat everyone similar it is not discriminatory, even if it is in direct violation of a law...
Then there is the Family Medical Leave act scam...sorry for rambling...
