According to “ifoAppleStore” (http://macte.ch/qgwUc) Apple is revising its scheduling practices “that will pressure employees who are already suffering from larger crowds of visitors.”
The article says Apple is changing weekend work requirements, and increasing the mandatory minimum hours for part-timers. “The changes seem to have substantial benefits for Apple, but few for its employees, and could result in many resignations from employees who are unable to comply with the new requirements,” opines “ifoAppleStore.”
