Postal workers are indeed categorized as federal employees in the United States. They work for the United States Postal Service (USPS), a federal agency responsible for mail delivery and postal services across the country. Postal workers fulfill various roles, including mail carriers who deliver letters and packages to homes and businesses, as well as clerks who sort and process mail in postal facilities. As federal employees, they receive benefits such as health insurance, retirement plans, and protections under federal labor laws. The USPS operates independently but is subject to federal regulations and oversight to ensure efficient operation and service to the public. Postal workers play a critical role in maintaining the national postal network and are integral to the daily functioning of mail delivery services nationwide.
