Over 50% of employees value happiness over pay

I’m not sure it is that simple. When searching for a new job, then salary is a big factor as you’ve got bills to pay. But maybe after being in the role for a while and you find that you are enjoying it (for whatever reason), pay isn’t so important? Alternatively, if you are on a really good salary but hate the job, would you stay just for the money? What are your thoughts?
