Firefighters are on strike tonight, from 6:30pm to 11pm. It's the second time they've staged a walkout.
But whereas their last protest was on a warm September afternoon, tonight they're taking action when bonfires are being lit around the country, and the risk of accident is that much higher.
One fire chief says she's been advising organisers of firework displays to postpone them - until the unions return to work.
Andrea Thomas has been speaking to Geoff Licence, who's running a fireworks display in Bearsted, near Maidstone and Ann Millington, the Chief Executive of Kent Fire and Rescue Service.
