On February 1, 1842, a private carrier Alexander M. Greig from the city of New York established the City Despatch Post, which covered New York north to 23rd Street. A few months later Greig sold the City Courier Post to the US government. Over the past centuries, the USPS has evolved into a powerful state structure, bringing a good profit to the country's budget. This is one of the largest employers of the public sector of the US economy - and its employees have quite significant benefits. For postalease job bidding visit the USPS LiteBlue website.
