The union represents 21 workers at the glass tube factory on Wheaton Avenue, or about half the labor force.
But 11 of those workers won't be recalled for about four weeks due to reduced business volume, said Joe Plumbo, the owner and chief executive officer.
A major issue in calling the strike was whether three inspector positions would be reclassified as non-union salaried jobs. The firm had asked for the change and got most of what it wanted.
"Basically, inspectors will be salaried positions -- with some conditions," Plumbo said.
The firm needed the concession to stay competitive against companies in China and South Korea, Plumbo said.
"We gave on everything," said shop steward Jill Sanderlin, who is expected to return in four weeks. "We just hope everyone's back to work soon."
