ROCKLAND — The Farnsworth Art Museum has laid off four employees and is requiring full-time, salaried staff members to take off a week of unpaid days later this year to bring down costs.

The museum is also postponing some new programming until its economic situation looks brighter.

Spokesman David Troup said the museum has not been immune from financial difficulties that have hit museums around the country.

The Farnsworth is one of Maine’s most prominent art museums, and includes a gallery and study center devoted to the Maine-related work of N.C., Andrew and Jamie Wyeth.
