I rent a commercial post office box. The USPS won't deliver packages to them.

I'm pretty sure the reason has to do with the law rather than USPS union vs private sector. It's about who has access to a mail delivery box. The addressee and the postal service, not the addressee, the postal service and various retail clerks that happen to be working that day.
