Warrensburg Board & Paper Corporation voted 15–14 to join the United Paper Makers and Paper Workers AFL-CIO. Within a week of the vote, the Corporation reported irregularities to the National Labor Relations Board in an attempt to prevent unionization. In December of that year, the Union and Company entered into a series of negotiations through which the Union succeeded in most of its major demands, gaining agreement to an employee insurance plan, a Union bulletin board, free access to the mill to contact employees, grievance discussion rights, and wage increases. When the Union failed to agree upon what steps to take next, the Corporation claimed the disagreement among members was in-fact a rejection of the Union, and the Corporation refused to agree to a long-term contract with the Union. When the NLRB ordered the corporation to return to the negotiation table, the corporation was sued by the NLRB and compelled by the court to return to negotiations. On July 14, 1974, the paper mill operated by the corporation was partially destroyed by fire. On April 3, 1976, flooding of the Schroon River, brought on by spring thaws, started to peak. The next day, the reservoir of the dam had raised so high as to completely surround the paper mill with water and cause outbuildings, train tracks, and pollution to be disturbed. Route 418, which runs parallel to the river, and a bridge located about a quarter of a mile upstream of the dam were shut down. The afternoon of April 4, under the direction of the New York Department of Environmental Conservation, two mill employees, using a backhoe and bulldozer owned by one of said employees, and aided by several private individuals, dug a ditch in approximately two and one-half hours, to alleviate the up-river flooding. Consequently, there was serious land erosion to the property adjacent to the dam and, the next spring, serious deposits of silt from the erosion was washed onto the Sit'N Bull Ranch and 1000 Acres Ranch, both located downstream. Since 1979, the Warrensburg Chamber of Commerce has been hosting an annual event known as the "World's Largest Garage Sale." During this event, residents and vendors sell their wares in a town-wide garage sale.
