This is such a weird take. Why would employees do that? Employees benefit when the company benefits. If the company increases profits by 10%, that's 10% more that could potentially go to employee benefits, salaries, etc.

I want my employer to make as much profit as possible, because that guarantees my long-term employment and allows me to ask for a higher salary. If the company folds, the union folds, and everybody loses their jobs. Nobody wants that to happen.
