They likely take lunch.
I was able to renegotiate things to 9-5, but my manager acted like it was this really unusual request and wasn't I lucky that they were willing to let me work "less than 40 hours."
That left me wondering, what do other people consider full time in this industry?
If you're in a part of town, for example, where it takes a 10 minute metro ride to get to the nearest restaurant, it seems illogical to enforce a half hour lunch.
