Lincolnshire fire crews could take part in more industrial action during the Christmas holiday period.
The Fire Brigades Union have announced a national strike will take place on Christmas Eve, New Year's Eve and January 3 in response to an ongoing dispute over pensions.
It has not yet been confirmed whether local firefighters will be involved in the walk-out.
Last week Lincolnshire Fire and Rescue took part in two evening strikes, both of which passed off without major incident.
During industrial action, skeleton crews respond to emergency calls, but do not attend automated fire alarm call-outs.
The national Christmas strike will last from 7pm until midnight on December 24, while the New Year walk-out will last from 6:30pm until 12:30am.
On January 3 there will be a morning strike from 6:30-8:30am.
Union representatives claim that more action is necessary because negotiations with the government have been unproductive.
