Perhaps you should try some spelling variations:
employee » employees
employed » employees
employeds » employeess, employees, employers, employes
co-operatives » co-operative, co-operativen, co-imperatives
co-cooperatives » co-cooperative, co-cooperativen, co-coimperatives, co-cooperation, co-cooperating

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((employee OR employed) OR employeds)-ownership & (co-operatives OR co-cooperatives) ) OR ( ((employee OR employed) OR employeds)-ownership & co-operations )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((employee or employed) or employeds)-ownership & (co-operatives OR co-cooperatives) ) or ( ((employee or employed) or employeds)-ownership & co-operations ))".
• Adding a wildcard symbol may retrieve word variants: (( ((employee or employed) or employeds)-ownership & (co-operatives OR co-cooperatives) ) or ( ((employee or employed) or employeds)-ownership & co-operations ))*.
