We have decent bike racks where I work. The bike gets locked during the day.

As a side note, we have a recording CCTV in the bike rack area as well. I used to think it would offer some additional security, or at least a way to recover stolen property. Well, some tools were stolen from that area, and it turns out the CCTV footage was/is so bad you can hardly tell whether the thief was human or alien. I don't know if they did anything to improve the image quality, but the cameras or their placement haven't changed. Don't rely on any help from CCTV unless you have seen actual sample pics yourself.
