A rally was held Saturday by Monterey County postal workers protesting the possible shutdown of the Salinas mail-processing plant. The protest was in response to a study to determine possible economic benefits of moving mail processing from Salinas to San Jose, a process that’s expected to last several months as well as close the plant and displace over 4-dozen workers. Protesters say closing the Post Drive plant would disrupt lives and employees could be transferred as far as 900 miles as well as delay mail.
