The independent survey contacted 1,480 employees across the country and found that employees are fearful regardless of their region or business sector.
YouGov found that almost half of the employees polled fear that they will not receive a pay rise while 33% fear an actual reduction in their earnings.
Over one in three respondents would consider either moving to work abroad or elsewhere in the UK and 31% of those polled are now considering taking on a second job.
An additional 21% are thinking of changing careers.
Andy Brown, managing director of organisational consulting at YouGov, says: “These results show how quickly employees are responding to the nose-diving British economy.
“Fears around job losses, stagnating wages and poor job opportunities have risen very sharply in the past few months.
“But in a positive response, many British workers seem prepared to ‘get on their bike’ to find work or to flex their working patterns to supplement their pay.”
He adds: “The challenge now is for British companies to find the best ways to leverage this new flexibility.”
