I'm always fascinated by these Billionaires who expect employees to work 24/7 for their company. Basically as an employee you give your company your work force against a salary, you don't sell your life to it.

As an employee you are not a samouraï ready to die for your daimyo.

If you don't have a life beyond your job, you are basically ready for your next burn out.

These Billionaires might commit 100% of their time to their company, but it is for their personal gain. On the other hand, as an employee, you will never really earn more than what was contractually signed on your contract, when they will tremendously benefit from your work, your creativity and your intelligence.
