LA GRANDE, OR—Roundy's Food Store stocker Jim Creighton felt ominously watched over by an employee time clock Tuesday as, at exactly 12:13 a.m., it noisily "clunked" over to the second-to-last minute of Creighton's 15-minute break. "Well, two minutes to go," Creighton mumbled grimly to himself, attempting to savor the final precious scraps of leisure time doled out to him by his employer. "Maybe I should grab another Pepsi." Creighton then sighed and stared at the coffee machine for the next 111 seconds.
