the owners of a company may also decide to hire new workers. this may cost less than giving into the demands of the workers. this is another way of breaking the strike. these workers, called "scabs" by strikers, are often yelled at as they pass through the picket line. many unions say that workers who helped break a strike by crossing the picket line are not allowed to be in the union. if the company is a union shop (meaning that only union workers can work there) this means that helping break a strike could get a worker fired from that company forever.
