Handling Workplace Disputes
Mediation; refers to the use third party person, who is neutral and abreasr with the conflict to solve the situation at hand and also to ensure that an agreement is reached.
Arbitration; this is usually done by the higher echelons of power in any organisation and in the medical field would include the chief doctors or human resource managers. The verdict given by the arbitor is final whether it fair to one party or unfair to another or not.
Second question is basically the performance contract document taking predominance and the code book of ethics- which also entail the need to mark the roll call and worker register. Use my line of argument in both questions and you will score highly.
