Firefighters walked out between 6.30am and 8.30am in continued protest over plans to reform the pension system.
However, only one call was made during the period, when a car became trapped in flood water in Mill Lane, Sindlesham at 7.08am.
Royal Berkshire Fire and Rescue Service (RBFRS) had contingency plans in place - with 11 engines available - and the driver and car were hauled to safety.
Andy Mancey, Acting Assistant Chief Fire Officer, said: “I would like to thank the public once again for taking extra care to reduce the risk of fire and for not calling 999 unnecessarily during this morning’s strike. I would also urge people to continue to follow our safety advice whether strike action is taking place or not.
“As the incident in Mill Lane this morning highlights, several roads in Berkshire are currently affected by flooding. Please do not put yourself and your passengers at risk by attempting to drive through flood water – it may add extra time to your journey but it is far safer to choose an alternative route.”
