Bosses have been urged to take note of new research that suggests unfair treatment at work can increase the risk of suffering a heart attack.
The British Heart Foundation (BHF) has noted that while work was only one factor, a feeling of injustice in the office could have knock-on effects elsewhere.
"Staff who feel unfairly treated at work may develop low self esteem which can contribute to stress, depression and anxiety," said Ellen Mason, a cardiac nurse at the BHF.
"This in turn, can make us much more likely to eat poorly, and eat and smoke more, thus increasing our risk of heart disease."
Ms Mason's comments follow a study published in the Journal of Epidemiology and Community Health.
Researchers found that people who felt they regularly suffered injustice had higher incidences of fatal and non-fatal heart attacks and angina.
"People in the 'high' category were 55 per cent more likely to have serious heart disease as those who did not feel they were unfairly treated and twice as likely to have it as those in the 'low' category," the researchers said.
