You are expected to USE confidential info. I don't think this counts as DISCLOSING confidential info.

Personal use is disallowed. From Amazon employee NDA[1], section 3.1:

"Employee will hold all Confidential Information in strictest confidence and will not acquire, USE, publish, disclose, or communicate any Confidential Information except as required in connection with Employee’s work"

Capitalization of USE mine otherwise verbatim.

If you know you're going to be going to NYC, how is this not "in connection with Employee's work"?

If the location of HQ2 hasn’t even been announced internally at Amazon, I don’t think any employee would know for sure they are relocating there.

Even if you were on the team who decided that on NYC and were charged to make it happen? I don't find it unreasonable to think that some key members of the team were set to relocate in and around the time the announcement came to pass. There is not enough information here to say if this is for speculation in real estate or personal use.

Heck at the rate of turnover and the job market they just could be a few employees leaving Amazon for a new position in NYC.

My company requires employees to sign a document that they won’t use confidential company info for personal gain.

If we go down that rabbit hole, are you allowed to perform well in your job using confidential information in order to gain a promotion?

The actual language specifies personal gain outside of work.

That said, I don’t think they have any mechanism to enforce it.

"We're going to ask you to move to New York, but don't use that to personally gain housing"?

The question is whether they bought that housing for themselves because they're being moved or if they bought it to resell at a profit because they had internal knowledge of this neighbourhood being used for HQ2.
