worker participation

[PHILLPS]

Can anyone give me some leads.  A colleague who is looking at the impact of work
er participation (profit sharing,
esop, worker involvement ect.) on productivity wants to know if there
are any national (comparative) surveys of the extent of worker part-
icipation and othe forms of involvement in economic decision making.
If anyone can give me leads as to any references on these points, I
would appreciate it.
