Final answer:
HR professionals should attach supporting documentation to the PAR form before submitting it for approval to provide context and justification for the disciplinary action proposed.
Step-by-step explanation:
Before submitting the disciplinary action Performance Action Review (PAR) form for approval, HR professionals should attach supporting documentation that provides proof and context for the disciplinary action being proposed.
This documentation might include records of prior incidents, warnings that were given, details of the employee's actions that prompted the disciplinary measure, and any other relevant information that justifies the decision.
Attaching this information helps ensure that the approval process is informed and fair. Ignoring documentation, creating temporary assignments, or skipping the approval process are not standard or advisable practices in this context.
