Up to a point. But gauging productivity is not an exact science in many business environments. As a mid-level manager, it was my job to assess the productivity of my employees and to make the case to higher level managers as to what those employees should be paid.
Paying an employee too much is an error just as paying an employee too little is an error.
I think Jordan Peterson points out that women tend to be more "agreeable" and thus tend to tolerate lower pay than a similarly situated man. This tendency explains some of the gender pay gap.
I don't remember anyone saying that workers should be paid too much, or there isn't a limit. Just, that it isn't a good idea/sustainable, to pay more valuable less than lower valuable employees.
There was another email that an employee was told they were the no. 1 employee for two years, but they weren't going to be eligible for a raise, and they were in the lowest tier of there compensation for that role. Than the company was surprised the employee started phoning it in.
And if a valued employee finds out they are paid less than others, don't be angry at the fact they found out. The company screwed around and found out.
That is a complete myth! It's calculated solely by total income earned. It does not take into account different jobs, hours worked, etc.
Men tend to pursue more remunerative jobs than women, including dangerous/undesirable ones.
Often men put in longer hours as well. If a true apples to apples comparison were done, women probably out earn men.
There was a female speaker that did some kind of talk in 2007, and even by then, 17 years ago, female millennials were making more money than their male peers for the same jobs.
I'm not sure why Freepers are spreading this myth.
