Overworking ourselves is overrated and unhealthy. Why is it so hard to respect work-life balance?

Why does our society perpetuate the idea that people must be constantly working in order to be worthy of respect?

I get tired of the way our culture fetishizes overworking. People contribute to this by competing over who has worked the hardest, longest hours as though overworking makes you a better person. This attitude can lead to a feeling of shame for taking a day off for being sick, tired, or needing a mental health day. In our very public, social media sharing society it can feel like we need to constantly “prove” how hard we are working to the watching world.
