Nearly two fifths of office workers would rather see a colleague made redundant to maintain or increase their own salary, a survey has revealed.
A total of 38% said they would be willing to see a workmate lose their job than see their own pay packet suffer, according to those polled.
But 62% of employees showed a more loyal attitude by saying they would be happy to take a drop in their earnings to save a colleague's position.
Almost half of workers surveyed (48%) said cutting back on lunch breaks would be the first office sacrifice they would make if forced to.
Giving up cigarette breaks came second (14%) followed by weekends off (12%) and company cars (8%), the survey of 500 people for officebroker.com found.
Chris Meredith, head of sales at officebroker.com, said: "Many people believe the way to motivate people is simply to give them more money but our results show that this view is far too simplistic.
"Nearly two thirds of those polled said they would be willing to take a pay cut to keep somebody else in the job which shows just how important a good team ethic can be in the workplace.
"For some people, money is their sole motivating factor so it's no surprise that more than a third of those surveyed said they would be happy to see a colleague fired if it would benefit them financially."
TUC general secretary Brendan Barber said: "Without co-operation, working life would be solitary, poor, nasty and brutish. However, there cannot be real trust at work unless workers feel that they have a voice, which is where trade unions play a vital role.
"Where there is no independent union to make sure that their views are properly heard, workers will understandably be sceptical about whether we are really all in this together, especially as they see top people's pay continue to soar."
