Machinists at the Bombardier Learjet plant have hit the picket line.

Traffic at the only gate left open for non-striking employees was backed up for more than three miles Monday morning as picketers briefly stopped cars attempting to enter the facility.

Company spokeswoman Peggy Gross said Monday the company is seeking an injunction that would give the company more control over picketers, such as how long they can hold up a car at the gate. She says the company plans to continue production, delivery and servicing of aircraft during the strike.

Machinists’ spokesman Tony Larkin says the union is ready to negotiate anytime. He says workers recognize the aircraft market has slowed down, but adds all the burden cannot be placed on workers without sacrifices by those at the top.
