Just do whatever your boss wants. Pick your battles. When you have your own dog and pony show, you can do it whatever way pleases you the most. I have a feeling that your boss's method must have used less copper.
There are 10 ways to do any electrical wiring job. Three of them don't meet code. Four of them are just silly or wasteful. That leave three ways. Your way, your helper's way, and your boss's preferred way. If the boss isn't around, do it your way. If the boss is around, or expected, do it his way. If you're having one of those "I don't care" days, let your helper do it his way. "Flexibility is the key to air superiority. It's how we beat the Russians."
