LEBANON — Timken’s Lebanon location informed workers Thursday that their hours would be reduced for 12 weeks this summer in order to adjust to “current demand,” a spokesman said Friday.

The cutback from 40 to 36 hours a week begins next week, Scott Schroeder, the spokesman, said. The change, which does not affect employees’ benefits, impacts 169 workers at the Mechanic Street facility, he said.

Timken offered the affected workers the opportunity to work a full 40-hour work week at the company’s Keene, N.H. location, which has openings.

“A number of them” have taken that offer and will be compensated for the extra travel time, he said.
