The resolution strategies refer to the stages in the dispute resolution process. They refer to the use of Grievance Procedures and consist of the following stages:
1. Formalising the complaint - often in written terms
2. Negotiation - talks between the two parties
3. Mediation - talks involving a neutral third party
4. Conciliation - formal negotiations
5. Arbitration - formal negotiations in an industrial court
6. Business Closure/Division.
They can also refer to the stages taken in the courts - called common law action, which refers to cases which are not covered by industrial legislation.
Hope this helps. Also if the question states anything about how the business can prevent conflict - talk about the points in the 'managing ER effectively' section.
