I was trying to use what I thought was a 220V receptacle at work but the
voltage was only 208V. When measuring, I see 120V between each hot and
neutral but only 208 V between the hot leads.

Am I really looking at two legs of a three phase Wye connected branch
circuit as opposed to a 220V single phase supply (common in residential).
Is this a common practice in commercial buildings?

Yes
