SAN DIEGOExecutives at Gortman Consulting are hiring immigrant day laborers to delete their junk e-mail. 'Our employees were wasting hours of valuable time sifting through spam,' Gortman CEO Donald Barris said Monday. 'Finally, I was like, 'Eureka! Hire some low-cost Hispanic laborers to empty our Outlook Express trashcans.' Our IT van just swings by the docks in the morning and picks up a dozen or so guys.' While Barris said the laborers are 'happy for the work,' labor-rights groups have complained that repeatedly pressing the delete key has caused numerous cases of carpal-tunnel syndrome among migrant spam removers.
