An industry survey has shown that 87 per cent of engineers questioned reported that they were either very or quite sure about their future prospects.
It shows that building services engineers are the most confidence among any of the trades surveyed by employee benefits company ECIC.
The survey found that 33 per cent of respondents had worked in excess of 50 hours a week last year and 21% had worked up to 60 hours a week.
Out of these, 30 per cent said they regularly worked evenings and weekends.
This had led to 18 per cent suffering from stress-related conditions such as high blood pressure, headaches and panic attaches, with 23 per cent considering alternative careers. However, nearly half (46 per cent) said that they had earned more last year than in 2013, while 39 per cent earned the same.
ECIC said the findings showed that greater employee support was required to retain much-needed skills and expertise, and to increase staff loyalty levels.
