Median pay: $53,080 of mail sorters, $53,100 for postal clerks
Declining mail volumes seem poised to send many mail-sorter and postal-clerk jobs to the dead-letter office. The BLS estimates America will have just 34,000 postal clerks in 2020 -- a 48.2% drop from 2010's 65,600. That's the third-biggest decline for any U.S. profession.
Median pay: $26,280
The BLS predicts employers will give 53.4% of all U.S. shoe-machine operators the boot between 2010 and 2020 -- the worst outlook for any U.S. job. The agency estimates total employment for shoe-machine operators, who run the factory equipment that makes shoes, will drop to 1,500 jobs as of 2020 from 3,200 in 2010. Morisi blames the decline primarily on offshoring.
