BA's Matchbox strike

Why is that some people are more inclined to strike rather then get a new job? I know that if I was not satisfied with pay & conditions at BA I would apply for a new job. These are not the days of the Bryant & May matchbox strike. The way Union leaders today go on about things you would think it was 1888. One thing, however, is certain - BA staff are not receiving 19th century pay & conditions. This is nothing other than the old Left flexing its muscle to destroy BA if it does not do what it demands. I have witnessed similar stories while working in London for the Civil Service in the 1980's. In the light of BA's £932 million loss over the past two years what the Unions demand is contrary to sound financial management in a recession hit world.
