You want people to work as much as possible to push the product and company out of uncertain territory into profitability, right? Wrong. What you will do is push people to the edge of burnout and unhappiness. They’ll eventually leave your company.
This is a management point I’ve been thinking about over the years: it turns out well rested employees are better long-term. I don’t think most (American) management believes that, at all.
The subtle point to make explicit here goes the other way: employees are work-gluttons if you let them be. They “over-eat” and can’t help themselves. Part of management’s job, then, is to help employees here.
Both management and employee are at fault, and there’s lots of work to be done.
