Several other electrical industries followed RCA to Bloomington. A former engineer for RCA, Sarkes Tarzian, went into business for himself after the war, manufacturing television tuners to supply to the large receiver producers, and eventually he moved into a variety of consumer electronics products and other components. As his shop grew from 900 employees in 1948 to more than 3,000 workers by the 1960s, again most of them women, organizing Tarzian's operation became a perennial goal for Local 1424 and the IBEW International office. Although they got close on several occasions, the union never won a certification election. Mrs. Tarzian was notorious for her extraordinary efforts at keeping the union out of the factory. She promised to build a swimming pool for the employees if they agreed not to vote for the union, and she was known to sit outside of union organizing meetings in an ineffective disguise to take note of the workers who attended.
