ATTLEBORO - An Attleboro company that makes precious metals used in the jewelry industry is laying off up to 300 workers.
Mayor Kevin Dumas says Cookson Precious Metals Division has informed the city that it plans to lay off 225 to 300 workers by March 31.
Dumas told The Sun Chronicle that the company notified him that it began the layoffs Nov. 1 as part of a phased reduction in employees. The company plans to keep its Attleboro facility open.
The British-based company is required by law to inform the city of the layoffs.
Cookson officials did not comment.
The company’s 193,000-square-foot facility has been the focus of efforts by local and federal officials for about a decade to clean up the contaminated site and keep Cookson’s jobs in Attleboro.
