Fortunately it is a smallish company (approx 300 people), there is one maintenance person who is part time and I know very well, and I'm one of only two people who ride in to work. I don't think most people even remember that we have a bike rack.

If the lock does show up missing, I have received permission before to bring my bike in and store it in the maintenance room or my office. Just not something I want to make a habit of as it could cause an office politics nightmare should a bunch of other people start riding in.. ("Why can he store his bike inside, but we can't? wah wah wah)
