//////why do men work better together than women?
Some time ago there was research suggesting that women brought a
different positive and nurturing perspective to the workplace. I'm
lookiing for research that that shows that is in fact not the case.
I've noticed this on reality TV: the women's teams fight; the men's
teams have fun. I'm wondering if there's academic/busienss research
that suggests that is widely true. Or that women bring special
problems to the workplace especially when working with women.

Just personal impressions that might not be supported by any research:
 women have told me (male) that a purely female working environment  -
a dept with a female department head -  is less attractive and maybe
less productive (very subjective  opinions, of course).

This may interest you:

"A new study has found that women professionals belonging to
all-female work teams are far more likely to want transfers from their
groups than men belonging to all-male teams, according to new research
by Professors Jennifer Chatman and Charles O'Reilly of Stanford
University.

While the men in this study were happy to be on all-male teams, their
contentment did not translate conspicuously into a greater commitment
to the company, enthusiasm for their work, or a spirit of team
cooperativeness. On these three measures, women on all-female teams
scored significantly higher than men on all-male teams.

What then accounts for women's unhappiness with all-female teams? It's
mainly a matter of status, according to Chatman, who holds the Paul J.
Cortese Distinguished Professor of Management at Haas, and O'Reilly.

They explain: 'Because of historical status differences between men
and women at work, women may have expressed a greater likelihood of
transferring out of all-female groups...in which the chances for
advancement may be constrained by being in a female 'ghetto'."

The study, which is published in the current issue (April) of the
Academy of Management Journal, raises new challenges for the managers
of project teams."

An attractive woman in the workplace is .. distracting

An intelligent woman is manipulative

Women menstruate in unisom (hormonal)

Men go for a beer in unisom

Men have no option but to work, the /average/ woman can always find a provider.

Men are predictable - women are normally minefields.

Men don't normally shag their bosses
- women often do

The list is endless

and given this one: wouldn't you rather work in a male dominate team?
