importance of a labor strike

Unions should go on strike if the workers are not happy.  People should never cross a picket line or scab (taking a job from a struck plant or store).  people should boycott any company who's workers go on strike.

The importance of labor unions and competition

Labor unions are important.  They ensure freedom in the workplace.  Many unions police themselves.  When I say this, the unions ensure that they do quality control.  Labor unions also help competition in markets, and workers can sometimes come up with briliant ideas.  An important union function is keeping management from taking advantage of workers by having an important weapon - the strike and the picket line.

Competition in the market place is important because it ensures lower prices, fights inflation without price fixing and ensures quality of the products and goods and services.
