A union can picket, boycott, or use a work slowdown to support strike efforts. Why would the union choose one of these over the other?

What will be an ideal response?

Answer: To support a strike, a union faced with an impasse has recourse to additional legal activities. In picketing, workers march at the entrance to the employer's facility with signs explaining their reasons for striking. A boycott occurs when union members agree not to buy the products of a targeted employer. Workers may also urge consumers to boycott the firm's products. Another alternative to striking is a work slowdown. Instead of striking, workers perform their jobs at a much slower pace than normal. A variation is the sickout, during which large numbers of workers call in sick.
