This document summarizes the key points around unfair dismissal for lack of capability. It explains that capability refers to an employee's skill, aptitude or health for performing their job duties. Dismissals for capability must be both procedurally and substantively fair, following steps like a proper investigation, notice of issues, an opportunity to improve, and a right to appeal. Common examples of capability issues and factors for determining the reasonableness of dismissals related to long-term absence or persistent short-term absence are also outlined.
