"The company maintained 'nothing in ERISA required the plan administrator to provide plaintiffs with details about their individual service calculations,' but [a federal district judge in Ohio] disagreed.

Specifically, [they] asked for 'a breakdown of hours awarded for each year and an explanation of why years that were credited less than one were not credited as full years.'"
