I've been discussing with a few people about a certain phrase in a piece of co-authored writing that bugs me. I can't put my finger on it, but half of us think the phrase is correct, the other think it is incorrect.

It's evident what is trying to be said with the phrase, but the "and, when time" part sticks out and feels wrong. The ones who think it is incorrect suggest the following tweak.
The workers have been trained on how to continue the construction, and, when the time comes, to man the structure.
