In the Bethlehem Steel Company's plants the strike was not very effective. This was due principally to the failure of previous strikes and to general lack of organization. In Reading and in Lebanon there had been strikes on for many weeks before the big walkout. The workers' ranks there were already broken. In Sparrows' Point likewise several departments had been on strike since May 3. Not more than 500 men, principally laborers and tin mill workers, responded to the general strike call; but they made a hard fight of it. In Steelton the men had been very strongly organized during the war; but the error was made of putting all the trades into one federal union. Then when the craft unions insisted later that their men be turned over to them, the resultant resistance of the members, and especially of the paid officers, virtually destroyed the organization. When the strike came only a small percentage struck, nor did they stick long. Speaking of the strike in the main plant at Bethlehem, Secretary Hendricks says: The strike was called September 29, and about 75 per cent. of the men responded. These were largely American workers. The Machinists, which comprise about 40 per cent. of the total workers, were the craft most involved. In the mill and blast furnace departments, the response was among the rollers, heaters, and highly skilled men generally, which led to the complete shut-down of these departments. The molders practically shut the foundries down. Electrical workers, steamfitters, millwrights, and general repairmen responded well. The patternmakers did not go out. The first break came a week later. It was charged largely to the steam engineers, who heeded the strike-breaking advice of their international officials and returned to work. Another factor was the failure of support from the railroad men on the inter-plant system. Had these two bodies of men been held in line by their officers, the Bethlehem strike would have been a success. In the Bethlehem situation too much reliance was placed in the skilled trades; more attention should have been given to the organization of the real fighting force, the unskilled workers. Another mistake was to have allowed the strikes to take place in Reading, Lebanon and Sparrows' Point. Even a tyro could see that they had no hope of success. Those men could easily have been held in line until the big strike, to the enormous strengthening of the latter. The National Committee had little to do with the Bethlehem situation before the strike, the movement developing to a great extent independently.
