Answer: Distributive bargaining
Explanation: The two sides (Labor and management) are engaged in distributive bargaining as both sides are of the opinion that any gain by the other is a loss. Distributive bargaining is defined as an adversarial competitive bargaining strategy in which one party gains only if the other party loses something and is employed during negotiation in the distribution of fixed resources between both the parties. This is usually because the goals of one party does not align or are against the goals of the other party resulting in a win-lose situation.
