Firefighters across Cumbria are taking part in a nation-wide walkout this morning.
It is the third time this year that they have taken action in England and follows a dispute over proposed changes to their pensions.
Firefighters have today announced that they will hold a fourth strike on pensions between 10am and 2pm on Wednesday 13 November in England and Wales.
The announcement follows a dispute over proposed changes to their pensions.
Firefighters in Cumbria will go on strike on Friday evening between 6.30pm and 11pm in a row about pensions.
Cumbria County Council says the service will be stretched, but they have enough on-call fire fighters to keep people safe.
