For me I never understood companies, since all they seem to care about is to force wages as low as possible instead of caring about the good of their people (and a company is nothing but a grouping of people) and to take on contracts/projects/commitments they can't meet out of greed.

When given a choice, people prefer not to be overworked due to poor management/scheduling/greed. When given a choice, people prefer to have stability in employment. This is demonstrated by the fact that when they have collective power these are two of the common items they negotiate for. Unions are created to promote their members interests. There, now you understand unions :) They represent the interest of their members not the companies interests and not letting workers pay the price for poor management/scheduling/overcommitments (I think this is where you are getting confused).

Unions don't care to 'force companies' anything, They care to represent THEIR members priorities. What you are promoting are a company's priorities which the company already looks out for and would be a strange thing for unions to form to then also promote.
