Assume that you are a management negotiator and the union presents the following proposal: Any overtime assignment will be guaranteed a minimum of two hours at time-and-a-half the base hourly rate for the classification. Previously, employees working overtime received time-and-a-half pay for the hours they worked but no two-hour guarantee. Indicate in some detail how you would cost out this proposal. Also, discuss some arguments the union might use to make it easier for management to accept this proposal (i.e., to reduce management's agreement costs).
