The Letter of Disagreement of Performance Appraisal is a crucial document in Canadian employment law that provides employees with a formal mechanism to challenge their performance evaluations. This document becomes necessary when an employee believes their performance review does not accurately reflect their work quality, achievements, or circumstances. It is typically used after informal discussions have not resolved the disagreement and before escalating to more formal grievance procedures. The letter must be drafted in compliance with both federal and provincial employment standards, including the Canada Labour Code and relevant provincial Employment Standards Acts. Key components include specific points of disagreement, supporting evidence, and requested actions for resolution. The document serves as an important record for both current dispute resolution and potential future reference.
