NACODS was much less willing to take industrial action than the NUM although many had voted for strike action when NUM members, which sometimes led to tension amongst workers in the mines. Militants in the NUM nicknamed NACODS the "National Association of Can-carriers, Obedient Dopes and Suckers". There were some confrontations during the
1972 strike, but nothing compared to what came in the
1984-85 strike. In April 1984, a small majority of NACODS voted to strike in support of the NUM, but this fell short of the two-thirds majority that their constitution required for a national strike. However, a deal negotiated by North Yorkshire NCB Director Michael Eaton persuaded NACODS leaders to call off the strike action in return to changes to the review procedures for threatened collieries. Ian MacGregor later admitted that if NACODS had gone ahead with a strike, a compromise would probably have been forced on the Coal Board. Files later made public showed that the Government had an informant inside the TUC, passing information about negotiations. ==General Secretaries==
