Solski became Local 598's vice-president in 1949 and was elected its president in 1952. Mine Mill's rivalry with the Steelworkers continued in full force during this period, and Solski had to fend off attempted raids on his membership. In what was presumably a bid to win the support of rank-and-file Steelworkers members, Solski actually pledged a significant amount of money for Steel in its battles against mine owners in
Northern Ontario and
Quebec during the early 1950s. Discussions over the manner of payment ended in acrimony, however, and ultimately no money was sent. In September 1958, Local 598 conducted its first ever strike at
Inco. Just before the strike, Solski held direct talks with
Ontario premier Leslie Frost in a bid for a negotiated settlement. The job action was resolved four months later, after negotiations with provincial
labour minister Charles Daley. Solski was defeated in his 1959 bid for re-election by
Donald Gillis, amidst a local backlash against Local 598's left-leaning leadership. Gillis was backed by the Steelworkers and favoured affiliation with the
Canadian Labour Congress; he also accused Solski of mishandling the union's funds, a charge that Solski angrily denied. Solski returned to an executive position with Mine Mill in 1960, winning election as the leader of its newly formed eastern district, which covered Ontario and
Manitoba. He was a frequent rival to Gillis in this period, and at least one meeting of Local 598 ended in a violent confrontation between the rival camps. Several years later, it was revealed that Inco had hired former
Nazis to disrupt the union's activities. The Steelworkers won the right to represent Inco workers in 1962, and Solski reluctantly joined the rival union. He did not return to a position of leadership. During his time as president of Local 598, Solski was regarded as an ally of Mine Mill's national and international leaders, many of whom were
communists. He consistently denied accusations that he was himself a communist or was acting under the influence of the Communist Party. The author Cameron Smith has written that Local 598 was never under communist control and was large enough to act on its own accord, without recourse to Mine Mill's national or international leadership. During the 1980s, Solski said, "I was the president of the largest local in Canada [...] I could tell the international president to go to hell if I wanted to." ==Return to electoral politics==
