fear their profits might be threatened.

Explanation:

Remember that a strike is a work stoppage, that means that the employes unite and concert agree to refuse performing the work they were hired to do. This until their demands are conceded. These demands usually are related to the increase of wages or the improvement of their empoyment conditions. Workers are concious that they are the ones that keep the productivity of a business or company. Therefore, if they refuse to work productivity will decay making the owners loose profitability. The market's competition doesn't allow these type of problems for a long period of time, so the main fear of the owners is related to their profits.
