The strategy that companies use to stop strikes from growing is to follow what the strikes want. Usually, a strike happens when the conditions of work or the distribution of wealth are uneven.
The company wants the workers to be productive again and the workers probably want to work again but with better conditions. It´s in hands of the company to either accept the demands of the strikers immediately or to try to negotiate with the union labor to reach a point.
I hope this answer helps you.
