The Towers Watson 2011/2012 Talent Management and Rewards study has some fascinating insights on the disconnect between what workers want and what employers think they want.
As can be seen from the chart below, the biggest disconnects are around job security and stress.
Workforce has a good article on the study and this topic. Key quote on their explanation of the disconnect:
"Why are employers burying their heads in the sand on job security and stress? It may be that companies feel powerless to do much about either. They can't guarantee absolute job security in an uncertain economy and may feel compelled to demand more and more of their workforce to stay afloat."
The lack of job security and increase in workloads and employment stress - the Workforce article calls this the "work-more economy" - are drivers of the growing interest in becoming independent or starting a small business.
