We have a similar bike rack at my workplace. I bought an On Guard 5009 Bulldog LS (a big honkin' keyed U-Lock) that I leave on the rack at work and use to lock my bike up when commuting. It is big enough to lock the frame and front wheel.
My workplace is very safe during daylight hours, and the rack is in plain view of the main windows. So this approach works for me.
Definitely consider leaving the U-lock at the work rack if you don't need it for other bike trips. Convenient and weight-saving. Also consider leaving a belt and shoes at work if you have extras you can spare and a place to keep them....
