Receiver Rick Land said Judge Stern ordered that termination letters be sent to firefighters, so each individual member of the department was aware of the situation.
The judge ordered the notices at a hearing in February.
The Central Coventry Fire Department is scheduled to shut down on May 16.
The union recently filed an appeal with the Rhode Island Supreme Court and the General Assembly is considering a bill to bring in a state-backed budget commission to Central Coventry.
Such commissions were used on Woonsocket, Central Falls, and East Providence to straighten out financial issues.
