I don't disagree with the guy on the "clock watchers" point but he should appreciate that in some cases people's circumstances push them to become "clock watchers". If they commit and produce excellent work during the time they are there then they should last.

Also, yeah, that doesn't make sense at all! It suggests they didn't a) read the job spec or b) believe in the company's values or c) perhaps the phrase was really "We value [when you] work [your] life [out of] balance" ;)
