Social and Environment Issues Missing in 2 Factor Theory?

Research Shortcoming Herzberg
Norman Dragt, Netherlands, Member

I think you are correct Pedro, but I assume it is caused by the research location, 200 accountants. Most accountants work in a surrounding that is strongly structured by regulation and laws, so job task setting is unnecessary as this is ruled by laws and rules from regulatory organizations. Also most accountants have a personality that likes hygiene.
So I agree that this theory lacks, but probably is very useful in well regulated jobs like accountant, lawyer, civil servant, etc.

Social and Environmental Values in Employee Motivation

In my opinion, social and environmental values (triple bottom line) adopted by a company could affect both hygiene and motivation factors, particularly if these values align with the employee's values.
