One of the company's employees, Holbrook, was discovered to have several union pamphlets in their desk, which led to suspicions of an attempt to unionize the workplace. The company president, N. Fredricks, made a statement to the Cambridge Police Department and Holbrook was eventually charged with sedition. Fredricks' statement, as well as the "Your Rights at Work" and "You-Nionize Today!" pamphlets, were transferred to federal officer J. Dobson.
