Jacobs Manufacturing Company (defendant) shared the costs of a group insurance plan for employees but did not have a pension plan. When negotiating a new collective-bargaining agreement (CBA), the union (plaintiff) requested that Jacobs pay all the insurance-plan costs, but Jacobs rejected that proposal. The parties entered a two-year CBA that did not mention insurance or pension plans, with a clause that allowed the parties to reopen discussions about wage rates after one year. When the union demanded wage increases a year later, it again requested that Jacobs pay all insurance-plan costs and establish a pension plan. Jacobs refused to discuss the plan requests, arguing the reopening clause did not cover them. The union filed unfair-labor-practice charges claiming Jacobs failed to bargain in good faith. The trial examiner found Jacobs had to bargain about the pension plan, but not the insurance plan.
