Apple has begun demanding more hours from both its full- and part-time retail staff, sources tell ifoAppleStore. While full-time employees are, for instance, currently expected to work at least one weekend day per week -- normally meaning Saturday or Sunday -- Apple is reportedly adding Friday to its definition of the weekend, and insisting that full-timers work two out of three days. Creatives, Geniuses, and Family Room and Red Zone Specialists are affected.
