Classifying a relationship as adversarial presumes a competitive context. I don't believe we are in competition with our employer but in a cooperative relationship, so we're talking game theory. A good employer cooperates with their employees to achieve business goals, a bad manager defects and prioritizes their personal goals/desires above the shared business goals. Your relationship falls out of this behavior (assuming no personal issues).
Isn't there competition for your own time? I'm thinking of crunches, or justifying a schedule despite workhour efficiency varying way too much (what are you going to achieve if you finish your last task at 16:40 on a Friday?)
What about a farm worker who tills the land? Is every farmer/farm worker achieving business goals through _cooperation_? What about seasonal farm workers? I guess the farmer can set up incentive payments, but even so, are you saying there no adversarial component to the relationship?
Any relationship can be framed however in different ways that embody different ideals. What one person views through an adversarial lens, another can view through a cooperative lens. All (above board) worker/employer relationships can be seen as cooperative. Neither entered into the agreement by force and each is getting something out of it.
