REVERE, Mass. (AP) — Employees of a Massachusetts candy plant who recently lost their jobs are suing the Connecticut-based company that laid them off.

The New England Confectionery Co. closed suddenly last week, and according to workers in the lawsuit, did not follow federal layoff protocol.

Dexter Main, of Lynn, and Francesco D'Amelio, of Revere, filed a class action Friday, alleging that the company owes the nearly 230 laid-off employees 60 days of back compensation.

They say Round Hill Investments and its management affiliate, Sweetheart Candy, failed to warn employees about the closure.

The suit is filed under the Worker Adjustment and Retraining Notification Act, which requires at least 60 days' notice for layoffs. Round Hill had announced July 24 it was shutting down NECCO.

The companies involved have not replied to a request for comment.
