The effects of the Darlington case on managements prerogatives was that it spelled out what a multi-plant employer must do in the area of plant closure to avoid violating the National Labor Relations Act of 1935. There was also good evidence brought forth to show that management is now bargaining plant closures with union. Thus the conclusion was made that in the area multi-plant employers had lost some power due to the Darlington Case. The General Case is presently in the Courts and until a final court decision is made it is hard to say what effect it will have on managements prerogatives.
