NORWICH – The International Chemical Workers Union at OSG Pharmaceuticals may strike if current contract talks don’t go their way.

The union members held a strike vote prior to labor negotiations that were supposed to begin in December, but the talks were pushed back to Jan. 3.

The union’s meeting was open to all 219 members; 161 attended, voting 157 to 4 in favor of giving the power to declare a strike over to the union bargaining leadership, said Local Union President Gary Robbins.
