If it is not your company, if you don't own a large share of it, then work your hours and switch off. Any bullshit about putting in extra work because you are in a "leadership" position is just that, bullshit to extract more value from you and transfer it to the company.
Do what you are paid for, no more, no less.
I worked for a startup that went out of business. You know how much sleep I lost when they were struggling? When they did finally kick the bucket, I called a few people in my network, got another job and kept it moving.
The question is business owner or not. While some CEOs are also business owners, many are not, particularly for publicly traded companies.
If you are the owner of a startup, constancy, or plumbing company you put in the hours you want to maximize company profit. It is your profit!
If you are an employee, (CEO or otherwise), you put the hours you want to maximize your compensation. If putting in 80 hours vs 40 hours has no impact on your pay stub, don't do it. you don't keep the extra profit...
They are doing what they are paid for. If I get offered tens of millions of dollars a year I would also consider putting in more than a 40 hour week. But I don't, so I don't.
My interpretation is not to ruin my health for a company I hold less than 0.5% stock (options) in. The amount of skin I have in this game is not enough to make me sacrifice the little pleasures that keep me sane.
I agree but don't ruin your health for a company you do hold significant stock in either.
There is hard work and pulling your weight. There is having faith in your vision and giving it your best shot. And then there is being just plain stupid and making yourself ill or worse for something that is still only about money in the end.
But that's true for non-leadership roles just as much.
So I read it as, even if you're in a leadership position, the company isn't yours, so you don't need to act as if it is.
