What type of letter warns of potential future disciplinary action that does not warrant immediate discipline?

An advisory letter serves as a proactive communication tool that warns an employee about potential issues that could lead to disciplinary action in the future. It is not designed to impose immediate discipline but instead aims to provide guidance and an opportunity for the employee to correct their behavior or performance before any formal action is taken. This approach encourages improvement and clarification, allowing the employee to understand the concerns without the direct consequences that accompany more severe disciplinary measures.

In contrast, a warning letter typically indicates that the employee's behavior is unacceptable and may lead to further action if not corrected, suggesting a more urgent tone. A disciplinary notice formally outlines specific infractions and the resulting penalties, reflecting a higher level of seriousness. A notification letter is a more general term and does not specifically convey the intention of warning about future disciplinary action.
