To become regular for the City Carriers, it'll take about 2-4 years and Rural side up to 7 years before you make it. Sucks, but when you need a job that pays well, USPS is your place. Because they work you 7 days a week most of the time (a lot) until you become regular and earn your days, sometimes you will be feel exhausted. Yes, you make good money but can't do your laundry or hangout with your family anymore. They should give an assistant a break too that they deserve. Also, when you're an assistant you will be required to work on Holidays, federal, etc. while the rest of the post office are closed. You will be delivering packages only, no mail. Overtime is the norm. Great place to work at if you're single.
