bar staff will be wearing T-shirts urging customers to think about how drunk they are and how their behaviour is changing during nights out over Christmas and New Year.
The T-shirts will be handed out to workers in Chesterfield as part of the Gauge Your Behaviour campaign being run by Derbyshire County Council, Derbyshire Police, Crimestoppers and community safety partnerships.
It will focus on reducing alcohol-related crime, including violence and anti-social behaviour by encouraging drinkers to consider how their behaviour changes when they drink to excess.
The campaign will be funded by the county council and the police.
It will be staged in Chesterfield every Friday and Saturday night throughout December.
Multi-agency teams will be out talking to people about how to stay safe.
Revellers will also be encouraged to report any information they have in relation to alcohol-related violence to Crimestoppers.
Derbyshire County Council cabinet member for public health, Coun Carol Hart, said: “We want everyone to have a great time when they’re out and about in our town centres this Christmas and New Year but excessive drinking by some can spoil it for others.
Superintendent Gary Parkin who is responsible for the police response to alcohol-related harm, said: “This is a real partnership effort.
“We are particularly pleased with the response we have got from licensed premises who will play a key part in the delivery of this campaign.”
