Unionized nurses at Baystate Franklin Medical Center are locked out.
Dozens of them were escorted out of the building last night after Baystate officials said the action was in response to a one-day strike.
The nurses say the hospital needs to address a staffing shortage, and the two sides have been working on a contract since last fall, but talks have stalled.
Temporary nurses will be working in place over the 72-hour lockout.
