On Aug. 2, Imerys locked out members of the Boilermakers (IBB) and brought in replacements at its talc plant in Three Forks, Montana. The lockout comes after Imerys consistently has refused to back down from its anti-worker contract proposal. The proposed contract would eliminate retiree health insurance, seniority, overtime over eight hours, double-time pay for overtime and the current defined contribution 401(k) plan, and would freeze the defined pension plan.
