The United States Postal Service processes more mail than any other postal system on the planet. Sorters, processors, and machine operators - often known as mail processing clerks - are responsible for organising this crucial stream of letters and packages. Mail may be sorted by hand at small post offices. Large electronic letter sorting machines and computer scanning equipment are used in larger institutions. 

These federal employees ensure that all mail is properly weighed and sent to its intended destination. This profession requires a quick and precise recall, solid coordination, and the ability to read rapidly and accurately. Many chores are carried out while standing, and there is a lot of lifting and reaching. 

Sorting and processing an infinite stream of mail can be tedious and difficult during busy mailing seasons. Shifts at night and on weekends are typical. Most postal workers receive on-the-job training, but you must meet specific criteria to be considered for a career in this area, and competition is fierce. 

You must be at least 18 years old, a high school graduate, and a US citizen or permanent resident alien. You must also be physically fit and pass the postal service exam, as well as machine aptitude and drug testing. Then plan on waiting a year or more before even a part-time job becomes available. 

Because of its low training requirements, good benefits, and job security, this is a vocation that will continue to attract more applicants than openings.
