> People familiar with the company’s retail plans revealed that Apple employees on Monday were asked to sign non-disclosure forms. Those who did not sign are said to be excluded from the next employee meeting, expected to be held in the next week.

Any employee of Apple Retail signs an NDA when accepting the job offer. There would be no reason for them sign any additional NDA for any special event. And no one would be blocked from a “secret meeting” for not signing their NDA. They’d be terminated. Immediately.
It’s a condition of working for most companies, not just Apple.
