A non-EU European country has recently been paralyzed by the direct action of truck drivers who are angry at a package of regulations that the government is considering introducing. Discussion between the government and representatives of the truck drivers is now taking place at a secret location to try to resolve the dispute. Three issues need to be resolved:

1.the maximum number of hours the drivers can legally drive per day,

2.whether or not the government will introduce a special fuel tax and

3.whether or not charges will be made against ten drivers who have been arrested during the dispute.

The possible number of driving hours that could be agreed are given below, together with the chief government negotiator's rough assessment of the values which each side would place on each outcome (100 = best outcome, 0 = worst outcome).
