Welch joined General Electric in 1960. He worked as a junior chemical engineer in Pittsfield, Massachusetts, at a salary of $10,500. In 1961, Welch planned to quit his job as junior engineer because he was dissatisfied with the raise offered to him and was unhappy with the bureaucracy he observed at GE. Welch was persuaded to remain at GE by Reuben Gutoff, an executive at the company, who promised him that he would help create the small company atmosphere Welch desired.[7] In 1963, an explosion at the factory under his management blew off the roof of the facilities, and he was almost fired for that episode.[8]
Welch was named a vice president of GE in 1972. He became senior vice president in 1977 and vice chairman in 1979. Welch became GE's youngest chairman and CEO in 1981, succeeding Reginald H. Jones. By 1982, Welch had dismantled much of the earlier management put together by Jones and led an aggressive simplification and consolidation initiative. One of his primary leadership directives was that GE had to be No. 1 or No. 2 in the industries it participated in.
