Managers used to believe that male employees where successful when they were mean, macho, roughnecks. Today’s best managers know that jettisoning unnecessary macho behaviors can be more beneficial to an organization than will stereotypical masculine behaviors. Male employees have been found to be successful when they admit mistakes, publicly appreciate their fellow male employees, and talk about the stresses that they face on the job. The characteristics that make male employees successful today include: being open to new information, challenging their assumptions about how things should be done, and admitting when they are wrong.
