Part of working with humans and managing humans is understanding they're human and not machines. And keeping those humans happy does very much impact the bottom line. If spending 20% more effort on a project retains engineers that speed up projects by 30% then it's a net gain for the business. Bad companies and managers don't understand that and then wonder why all their engineers are bottom of the barrel (or rather why their projects end up such disasters while those of their competitors don't).
