Answer:
Sympathy
Step-by-step explanation:
A sympathy strike is one in which a group of workers go on strike in support of another group that has a dispute.
This can occur even when the group going on sympathy strike do not have a dispute to settle with their employer.
Sympathy strike is not viewed as a violation of no strike clause in an employee's contract.
In the given scenario United Auto Workers went on strike support the employees of the Detroit News, Detroit Free Press, and USA Today.
