More than 100 machinists went on strike this week after they failed to reach a contract agreement with a York-based parts maker.

The 121 employees of Precision Custom Components went on strike at 12:01 a.m. Tuesday because proposed health care coverage increases were too high, said Randy Jones, representative for International Association of Machinists and Aerospace Workers Local Lodge 1403.

"We would need a $5-an-hour raise to cover the new deductibles," he said.

Management at Precision Custom Components, a military and nuclear parts manufacturer at 500 Lincoln St., proposed a series of increases during the next three years, Jones said.

Beginning Jan. 1, deductibles for a single person would increase from $200 to $2,000, and those for a family would increase from $400 to $4,000, he said.

On Jan. 1, 2017, they would increase to $2,500 for an individual and $5,000 for a family.

"We don't understand it because the company is making a profit. We're willing to get back together and negotiate, but as of now there's been no response from the company," Jones said.

A human resources representative at Precision Custom Components did not return multiple calls seeking comment.
