The places in our region where workers are most likely to be naughty or nice the day after the office Christmas party have been revealed.

A survey by hotel group Travelodge say revellers in Sunderland are most likely to feel the effects of a hangover - leading to loss of productivity - on the day after the night before.

They say Mackems top the league table with 64% lost productivity followed by Newcastle workers at 61%.

But you’ll be celebrating if you’re a boss in County Durham.

There they have the most well-behaved workers will a loss of just 38 per-cent productivity on the day after an office do.

Elsewhere in the region, however, bosses will be tearing their hair out as the workforce lets their hair down.

The hotel group say there will be a total of £22m in lost man hours as bleary-eyed staff struggle to do their jobs.

The survey also look at the places where workers are most likely to pull a sickie by phoning in to say they won’t turn up to work at all.

It said workers in Gateshead, Hartlepool and Darlington are the worst offenders.

The company surveyed 1,000 workers in the region to find out the latest trends about the office do.

They said: “On average, adults will be spending £56 on sprucing themselves up in order to impress work colleagues at their annual work’s bash.

“However all of this partying is not great news for North East employers as the post-Christmas party hangover will cost companies £22million in lost man hours.

“Key findings revealed that more than half (55%) of employees in the North East will waste half a day at work after their annual Christmas party because they are suffering the ill effects from the night before.

“Almost a third (30%) of workers in the North East will be twenty five cent less productive, and a fifth of adults will call in sick or show up late.

“The study also revealed that workers in Gateshead, Darlington and Hartlepool are more likely to pull a sick day following their Christmas works party.”

Shakila Ahmed, Travelodge spokeswoman, said the trend was for the average worker to attend two works parties and stay in a hotel rather than take a taxi home.

She said: “The Christmas office party season is certainly in full swing. Our city centre hotels in the North East, which cater for business customers have been getting booked up weeks in advance for the festive party season.

“Interestingly this year we are seeing more Christmas work events taking place on a Wednesday night. More workers are opting to stay in a value hotel this year, as it gives them an ideal place to get ready, get some much needed shut eye and it can work out cheaper than a cab home.”

Other research findings revealed women will splash out of a new outfit and hair and beauty treatments.

“The most popular treatments for women are a new hair style, a blow dry, a fake tan, eye lash tint and a manicure. Whilst for men, it’s a beard trim, haircut and fake tan..” says the company.

“Interestingly 56% of North East workers surveyed admitted doing something they regretted at their staff party. Among the top ‘faux pas’ are criticising co-workers, spreading gossip and sharing a cheeky kiss with a colleague.
