Very little progress was being made in the states in the passage of other industrial legislation. In Alabama and Massachusetts in the middle eighties acts extended and regulated the liability of employers for personal injuries suffered by laborers while at work.[5] At the same time the attitude of the legislatures and the courts in some states toward strikes underwent a slight modification. In many states where the legislatures had not passed definite statutes to the contrary, it had been held by the courts that strikers could be tried and convicted for conspiracy. In a few cases, states passed acts attempting to define more exactly the legal position of strikers. A New York court in 1887, for example, held that the law of the state permitted workmen to seek an increase of wages by all possible means that fell short of threats or violence. Before the close of Cleveland's second administration, considerable progress had been made in state legislation concerning conditions and hours of labor for women and children, protection of workers from dangerous machinery, the payment of wages, employer's liability for accidents to workmen, and other subjects. On the other hand, in some cases unreasonable or ill-considered actions on the part of the unions or their active agents--the "walking delegates"--turned popular sentiment against them. Particularly was this true in cases of violence and of strikes or boycotts by unions in support of workmen in other trades at far distant points. During the presidential campaign of 1892 a violent strike at the Carnegie Steel Company's works in Homestead, Pennsylvania, arose from a reduction in wages and a refusal of the Company to recognize the Iron and Steel Workers' Union. An important feature of this disturbance was the use of armed Pinkerton detectives by the Company for the protection of its buildings. Armed with rifles they fell into conflict with the workmen, a miniature military campaign was carried on, lives were lost and large amounts of property destroyed. Eventually the entire militia of the state had to be called out to maintain peace. It remained, however, for Chicago and the year 1894 to present one of the most far-reaching, costly and complex labor upheavals that has ever disturbed industrial relations in America. So ill understood at the time were the real facts of the controversy that it is doubtful whether it is possible even now to distinguish between truth and rumor in regard to some of its aspects.
