Whatever you call it, police are urging those knocking off work for the year on Friday to do so safely. 

Ballarat Police have said they will be patrolling licensed premises to crack down on liquor licensing breaches and anti-social behaviour.

Clancy Herring, a 24-year-old carpenter, said the end of year celebrations, known for all of the above names, were often "hectic".

"It's like something out of a movie. It's what you expect, everyone is knocking off for Christmas and they're all full of grog," Mr Herring said.

"All the brickies, chippies, plasterers and pavers, they're all at each other."

Mr Herring said people thinking of starting fights on the night should take their issues elsewhere.

"Drink at home and get angry in your shed if you are considering starting fights," he said.

Ballarat Police Senior Sergeant Peter Carey said people must think before they act.

"The last thing anyone wants is to spend Christmas with a court date hanging over their head," he said.

Senior Sergeant Carey said the onus is on both employers and employees to enjoy themselves safely and responsibly.

"Employers should set a good example and discourage dangerous behaviour like heavy drinking or drinking after functions when people are already alcohol affected," he said. 

"Where possible, employers should ensure there is plenty of food and non alcoholic beverages available." 

Ballarat Regional Trades and Labour Council secretary Brett Edgington said a minority of people ruined the fun for others.

"Have a few beers, but be respectful, safe," Mr Edgington said.

"At work and on your building sites you take your safety and the safety of your Comrades and Colleagues very seriously all year, take that approach on Friday night – look out for each other. Have fun and be safe.”
