A person familiar with the plan says NHL employees at the league offices will switch to a four-day work week Oct. 1 because of the lockout.
The cost-cutting move will effectively cut salaries by 20 percent. The person spoke on condition of anonymity Wednesday because the NHL had not made the plan public.
The news was first reported by The Canadian Press.
The Florida Panthers and Ottawa Senators have let staff go because of the lockout, while several other teams have said they don't have any plans to do so as of now.
The league locked out its players at 12:01 a.m. Sunday, its fourth shutdown since 1992.
