Striking Prince George's County nurses in the fourth day of their walkout yesterday had a few tense moments when they came to get their paychecks for last week's work.

Strikers at Prince George's General Hospital thought they would have to surrender their identification badges and auto parking cards following issuance Wednesday of a hospital memo saying the credentials would be collected when the strikers came for the paychecks yesterday.

However, the nurses' union lodged a complaint with hospital management officials, noting that none of the nurses has been terminated, and the memo was rescinded early yesterday, a hospital spokesman said. Paychecks were picked up without incident, according to union officials.

The nurses on strike had a setback yesterday when a Prince George's General doctor asked them to move out of a house he had loaned to them to use as a strike office. Union officials said Dr. William Holbrook gave no explanation for retracting his offer, and he could not be reached for comment yesterday.

Meanwhile, officials at Prince George's General and Greater Laurel-Beltsville hospitals and the Bowie Health Center say things are going well despite limited staff. Negotiators for the nurses and the corporation that runs the facilities are scheduled to meet Tuesday with a federal mediator to see if stalled talks can be reopened.
