Members of the International Association of Machinists and Aerospace Workers, Local 692 walked out of 25 locations across the province on June 22.
The union says members voted on a revised offer by the company after mediation ended on July 7 but yesterday announced they turned the proposal down.
The union says the dispute is over wages, benefits, shifts, subcontracting and the duration of the agreement.
Stan Pickthall, with the union, says members “agreed to zero per cent when the company was in trouble two years ago,'' but argues times have changed after Finning reported “record profits'' for the first quarter of 2011.
Equipment and parts sales were to continue during the strike but Finning has said shop and field services are suspended, affecting customers from Vancouver Island to southeastern B.C. and north to Terrace, Tumbler Ridge and Fort St. John.
