Every year, we do an employee survey to see how management is doing; like a report card for management. In the last 3 years, mine has come back with the highest company scores for employee engagement, job satisfaction, and project completion rate. I was asked to give a presentation to the other officers and managers about things I do to get those scores.
The presentation was basically one slide that I expanded to 10. It came down to creating the expectation, for the folks who report to me, that a work week is 37.5 hours (our full-time week) and no more. I make it clear that if my team is working overtime, I've failed. If that happens, together we look at their project commitments and reduce the workload, or get training, or whatever is needed.
Working folks to the point of burnout is NEVER a valid solution. Respecting personal time pays dividends to everyone. It's amazing how treating people like adults makes them happier and more productive. It's such a low bar and yet seems so foreign to people.
After my presentation, multiple execs argued thar I'd get more done if I pushed my team harder. Our company President pulled up all of our project completion rates, and asked them to explain the discrepancy. The three who complained the most about my approach were in the bottom five.
Data continually shows people are happy when they have a solid, predictable, work life balance. Happy people are more productive and are willing to do more in the long run. And they stick around, so you don't have to keep looking for new employees. Everyone wins. Yet, there is such a resistance to it by certain people, and I don't understand why.
Tldr: Expecting your people to give up their personal life for work, it's a clear sign that you are a terrible leader.
