BANGOR, Maine (AP) — Nurses at the Eastern Maine Medical Center in Bangor are on strike.

A number of nurses are picketing the hospital on today for what is supposed to be a one-day strike.

The strike follows a two-day lock-out imposed by hospital administrators prior to the beginning of the strike.

The hospital hired 215 replacement nurses to work during the lockout and strike.

The nurses contract with the hospital expired Sept. 30.

Among the issues separating the two sides were nurse staffing levels, health insurance costs and the practice of moving nurses from one specialty unit to another against their wishes.
