This is so obvious.
The psychological and physical problems of burned-out employees, which cost an estimated $125 billion to $190 billion a year in healthcare spending in the U.S., are just the most obvious impacts. The true cost to business can be far greater, thanks to low productivity across organizations, high turnover, and the loss of the most capable talent. Executives need to own up to their role in creating the workplace stress that leads to burnout—heavy workloads, job insecurity, and frustrating work routines that include too many meetings and far too little time for creative work. Once executives confront the problem at an organizational level, they can use organizational measures to address it.
But its also your repsonsibility to balance your career plans & mental hygiene. Once you start over-working, thats becomes the level of expectation. I’ve learned that overachievement is not rewarded. You are the only person who suffers.
Your employer will take everything you have to give so that they get the money. Don’t do that.
