The O.C. Register reports online that Orange County's top five employers have announced they will lay off 2,500 employees in the coming year. The full list is topped by Irvine's J.P. Morgan Chase Bank, which plans to issue 514 pink slips, with Aliso Viejo's Marvell Semiconductor Inc. only sacking one person. (Of course, if you happen to be that employee, one is indeed the loneliest number.) The OCR operates a Handling Hard Times site, whose homey advice includes using restaurant email spam to dine out cheaply ("consider setting up a second e-mail account to use for all of your 'junk' type mail), and to use "'virtually useless' online job sites . . . as a starting point."
