I've not seen a policy or guidance document on that but have been involved in discussions about it. I was the guy going in on Sunday and at 4am to pickup a document I needed before I boarded my 5:30am flight. The problem is the person would likely want to be elsewhere so they're not happy, and you're not happy. But it can tend to be a necessary evil.
Key codes for entry help ID who is where, and when. And today it would be quite easy to have an employee with a key to text the security officer to announce their arrival. If management agrees this is a security issue, the first person drawn on when an armed guard clears the building or the first person held by the police on a weekend exiting the building with a silent alarm going off would likely agree, a text is not so hard. Scheduling a day in advance though, I'd vote against it.
Seek a negotiated result and write up what is agreed to, train staff with access, and remind them with email blasts what the SOP is.
