My family had a manufacturing business employing ~100 people.
When orders spiked, we found the performance gain from working overtime was consistently short term. Much beyond 3-4 weeks wasn't worth the effort and expense, and a decision to add additional people or extend delivery dates had to be made.
That's not to say we couldn't get additional production out, it just did horrible things to the our cost structure.
I think what you're getting at is the belief that working longer is equal to harder.
