The saying goes that if you choose a job you love, you'll never have to work a day in your life. From the time you finish school until you're about 65, you'll be going to work almost every day – so it helps if you really enjoy it. But if you're not feeling fulfilled, new research could be the inspiration for a career change, it reports Metro.

The research of Reboot Online revealed the jobs (professions) with the happiest workers. And who won the first place? Employees in the scientific and pharmaceutical sectors were found to be the happiest, with a happiness rating of a whopping 91,93 percent. Science and pharmacy were also the most satisfied when it came to the individual well-being factors of mental health, work empowerment and salary.

The overall happiness score is determined based on responses to seven factors: positive impact on others, career prospects, employee empowerment, work relationships, positive impact on mental health, pay and work culture. More than 2.500 experts aged 18 to 70 from 29 different professions were surveyed.

Workers in the creative arts and design industry are the second happiest workers with a score of 83,81 percent, while environmental protection and agriculture are in third place with a score of 80,96 percent. Charity and volunteer work had an overall rating of 76,66 percent, with many workers satisfied with the positive impact their work had on others. However, charity workers did not feel valued by their employers and their satisfaction with pay and job empowerment was below 40 per cent.
