At a time when fire services are making cutbacks, one of the region's most rural counties says it needs more retained firefighters.
The Shropshire Fire & Rescue service has 23 stations, with all but four staffed entirely by on-call colleagues.
Retained firefighters are ready day and night to be sent to emergencies - but they also have day jobs.

Retained firefighters work shifts for the fire service at the same time as having their day jobs.
They can get paid anything between £5000 and £11,000 per year, depending on how much cover they can work in and around their normal jobs.
They must live and work within five minutes of their base fire station, so they can be kitted up and ready to deal with an emergency call-out 30 minutes after being alerted by pager.

Matt Lamb, the Secretary of the Fire Brigades Union (FBU) in Shropshire, says it's important to get the balance of retained firefighters and full-time staff right in a county like Shropshire.
