Do fluorescent lights last longer if they are left on?

I had a boss who said this, and I was wondering if it is really true.

I would rather replace them with non-fluorescent, but the fixture doesn't really allow that, and I don't have the skills to replace the fixture right now.

The lightbulb is very new and has a Phillips circline / circular fluorescent bulb with the following characteristics: T9, 4 Pin (G 10 q) 1 and 1/4 inch diameter (1.25).
