There should be a clear list for each employee of which specific things will get them fired. And which things need to be done for them to otherwise not be fired. And which things need to be done for them to be promoted.
Anything else you're basically saying: "If there is ever a lawsuit between this individual and the company, we will have to assemble the employment agreement in court from a variety of obscure emails and text messages."
What amazes me is that even with that risk, it still seems to benefit the company to keep these things vague in order to keep promotions down, and to make it easier to fire people who are doing their jobs. But I guess the numbers add up.
Woohoo welcome to the Meritocracy of American Capitalism
