Grievances arise from disputes between employees and management over violations of contracts, laws, policies or past practices. Common causes of grievances include issues with promotions, amenities, services, fines, compensation and more. The grievance process involves defining the situation, contention and remedy in writing. Grievances are addressed through informal and formal levels that may include meetings with supervisors, written submissions, and appeals up to board level. Proper grievance handling requires prompt investigation, hearing from all parties, and adherence to contractual timelines and procedures.
