Which of the following was a tactic that companies used to hurt unions? a. hiring scabs b. firing all workers c. using arbitration d. hiring the military

Hiring scabs, is the right answer.

Explanation:

A strikebreaker is also known as a scab is an individual who serves notwithstanding a continuous strike. Scabs are generally persons who were not contracted by the business before the trade union conflict but preferably hired following or through the strike to keep the business running. The practice of Scabs is a global phenomenon; nonetheless, many nations have enacted legislation preventing their employment, as they weaken the collective agreement process.
