How many postal workers?

Former PS-05 maintanance mechanic at the Brooklyn processing & Distribution Center here, couldn't stand the place or the mentality of the management so I didn't stay all that long. All the dust and lint in the air from processing letters would make my nose and throat itch, the noise from the conveyor system just wears on you after a while. Working nights and weekends kinda sucks anywhere you go but it seemed to suck more at the post office, you would have to wait for someone to either retire or die for a day shift position to open up, and speaking of the day shift, about 75% of the day shift employees had this beat down worn out look on their face (the about to go postal look) when they showed up for work in the morning, very few of them looked happy to be there. I didn't find the pay to be very competitive either for the amount of B.S. you have to go through to get in. Another thing I couldn't stand is the hurry up and wait mentality of management. The only good thing is once your in your in for as long as you can tolerate the job.
