Having worked in HR before, I can totally see this...
Apple decides to shift hours, thereby reducing hours for some staff members. At the same time a few other employees were terminated because they just weren't working out. Those few, now most likely unhappy, former employees see what has happened to them and see the reduced hours for others, and they sound the alarm about "mass layoffs." The hyper-sensitive media, especially when it comes to anything Apple, takes the word of a few former employees and runs with it.
There you have the situation we find ourselves in today. Apple tried a new scheduling process that didn't work and a few employees were terminated, which may or may not have had anything to do with the revised schedules.
