Workers and employers - adversaries or partners I

Given that some degree of cooperation is required if anything is to be produced, considerable room for conflict remains between labor and management. 

How serious will this conflict be? According to Marxists, the relationship between managers and workers in a capitalist system is inherently adversarial, since management’s goal (higher profits) can only be obtained at the expense of the worker’s goal (higher wages) and vice versa.

To strengthen their bargaining power and to protect their class interests in the face of management’s continual drive for greater profits, workers are inevitably led to form labor unions. From a Marxist perspective however labor unions are not the ultimate solution to the adversarial relationship. The ultimate solution is for workers to seize control of the state and substitute government ownership of capital for private ownership. 

Since the state will then be controlled by the workers, an adversarial relationship can not exist because the workers will be in effect their own bosses. This line of thinking was used by the Ukrainian government when it outlawed independent union. (If the state owns the means of production and operates them in the interests of the workers, why do workers need an independent union?) Events in Ukraine suggest however that the goals of managers and workers in a former socialist country may be in as much or even more conflict as those in a capitalist country.

In the auto industry (GM and Chrysler) workers thru their unions are the owners, can that idea trickle down from Detroit to New York City?
