But official support for organized labor ended when strikes closed factories that were important to the national war effort. President Wilson and his advisers felt workers should put the national interest before their private interest. They told workers to wait until after the war to demand more pay and better working conditions.
In general, American workers did wait. But when the war finally ended in nineteen eighteen, American workers began to strike in large numbers for higher pay.
As many as two million workers went on strike in nineteen nineteen. There were strikes by house builders, meat cutters, and train operators. And there were strikes in the shipyards, the shoe factories and the telephone companies.
Most striking workers wanted the traditional goals of labor unions: more pay and shorter working hours. But a growing number of them also began to demand major changes in the economic system itself. They called for government control of certain private industries.
Railroad workers, for example, wanted the national government to take permanent control of running the trains. Coal miners, too, demanded government control of their industry. And even in the conservative grain-farming states, two hundred thousand farmers joined a group that called for major economic changes.
All these protests came as a shock to traditional Americans who considered their country to be the home of free business. They saw little need for labor unions. And they feared that the growing wave of strikes meant the United States faced the same revolution that had just taken place in Russia. After all, Lenin himself had warned that the Bolshevik Revolution would spread to workers in other countries. Several events in nineteen nineteen only increased this fear of violent revolution. A bomb exploded in the home of a senator from the southeastern state of Georgia. And someone even exploded a bomb in front of the home of Attorney General A.Mitchell Palmer, the nation's chief law officer.
However, the most frightening event was a strike by police in Boston, Massachusetts.
The policemen demanded higher wages. But the police chief refused to negotiate with them. As a result, the policemen went on strike. When they did, thieves began to break into unprotected homes and shops. Massachusetts Governor Calvin Coolidge finally had to call out state troops to protect the people. His action defeated the strike. Most of the policemen lost their jobs.
All this was too much for many Americans. They began to accuse labor unions and others of planning a revolution. And they launched a forceful campaign to protect the country from these suspected extremists.
