Answer: hire; hire
Step-by-step explanation:
The Nash equilibrium for this game is for Management to hire a lawyer, and for Labor to hire a lawyer.
The Nash Equilibrium is the solution in a game where the parties are not cooperative with one another and refers to the strategy at which neither party would not want to move from as it would not benefit them to do so.
The Nash Equilibrium here is that they both hire a lawyer because if one side decides not to hire a lawyer, they could win only one tenths of the time. Both of them will therefore hire lawyers and neither would go without a lawyer on the chance that the other hires a lawyer.
