Does drinking after work work? (that is, does it lead to higher salaries)

By Paul J. Zak. Excerpt:

"Employees who drink after work have higher salaries.  Drinkers make 20% more than abstainers--an huge effect.  This effect is thought to come from the social connections one makes by socializing with work colleagues.  The original research was based on a survey of U.S. adults. 

But, is it really true that hanging out with your work buds will get you a salary bump?"

Dr. Zak did a controlled study but concluded there is no causation.
