The fallacy of "productivity"
Many business owners, particularly the self made ones; are famous for their "drive". I have personally heard things that would make your hair curl and then fall out. So called 'productivity" is the biggest lie perpetrated on employees.
The fact is that it is often the fault of certain employee's trying to agrandize themselves to management, that are the root cause of the problem. There are too many 'Suck ups" and "Yes Men" who devalue themselves and others by working for free.
Full time employment is 40 hours a week. Working 60 hours and not getting paid for 20 of them is the reason why people burn out and drop dead at their desks. Nobody can pay me enough to want to die for the company anymore. Working even more than 60 hours is the very definition of insane.
"At will" employment should be a thing of the past.
Productivity should be judged on quality not on quantity. Demands like the one from Musk or Gates are part of the reason that people are still unemployed. From now on, I'll check any prospective employers parking lot on the weekend and if there any cars there, I'll go somewhere else.
I for one would like to see overtime made illegal if required longer than 6 weeks. It should not be offered if there are any unemployed in the area.
Realistically, the legal definition of full time employment should be reduced to 32 hours/week and full health benefits should be paid pretax in full by the employer by the time the employee works more than 24 hours/week. MINIMUM VACATION should be 3 actual weeks (7 Days each) and should be fully paid.
This would do several things, like increase wages, decrease unemployment, balance workloads and in general make the quality of life better for employees everywhere. Not to mention the increase in service sector jobs needed to accommodate extra shifts and supervisory positions needed to manage more employee's. The increase in expendable income would more than pay for itself through other taxes. People would be happier and do better work.
That is the true measure of "productivity".
