More than a quarter of a million Britons get assaulted at work every year, it is alleged.
One in four Americans say their daily grind is also upset by angry customers or bullying bosses.
Now a Warwickshire company is offering help to some of the biggest business names, both sides of the Atlantic, in d efusing workplace aggression.
Fast developing SAC International chose Centenary Business Centre, the Warwickshire County Council incubator for small firms, from which to service its client base - at the same time as opening an office in Atlanta, Georgia to develop its business in the US.
And it seems the FBI, is looking at the Nuneaton firm's very specific skills.
The company launched the overseas expansion based on successful work, typically in the NHS, giving training to staff to help them avoid, prevent and deal with potentially violent situations.
Last year, hospital workers were subjected to an average of 32 cases of violent or aggressive behaviour every day.
SAC International managing director Jeremy Towler, from Bedworth, said: "After 15 years in the care and teaching business I realised there was a real niche for a company that could provide a service showing people how to deal with aggressive situations in a non-confrontational manner.
"I decided I had the necessary skills and experience to be that company."
SAC, which stands for Self Awareness Consultancy, has gone from strength to strength; last year it ran 519 training events that involved 10,380 people mainly working in Social Services, NHS Trusts and the Probation Service.
Mr Towler said: "Our training programmes are aimed at controlling the situation and defusing it at all costs - and we tailor that to suit people according to their job role."
A recent TUC survey of 5,300 workers claimed that almost half of Britain's employees had witnessed aggressive behaviour at work.
An estimated 18 million days' work are lost each year.
"Unlike schoolroom bullying, most workplace aggression is verbal or behavioural rather than violent," said head of operations Melissa O'Grady. "But mental bullying is just as stressful as the physical form. Our findings show that, with better management training and awareness, bullying is avoidable.
"Workplace bullying not only damages the individual but everybody who experiences it and no workplace is immune."
SAC International moved to Centenary Business Centre two years ago with two staff and now employs ten.
Centre manager Paul Kerr said that was exactly why the custom-built workspace facility had been set up.
He added: "The idea behind the Centre is to offer space to small and start-up companies, plus a range of business support services important to growing businesses.
"Here they can benefit from conference rooms and a postal service which means the physical space required for their offices is much less than usual."
Forty-three firms are operating on the site.
