For as long as the employment lasts. The disciplinary record is crucial documentation that you’ll need to rely on to defend the action and/or justify further discipline under a progressive discipline policy. POSSIBLE EXCEPTION: .Make sure the collective agreement doesn’t require you to get rid of the disciplinary files after a pre-determined period. This is a common provision that unions negotiate for so as to render an employee’s slate clean after a specific amount of time.
Last but not least, keep the records for at least 12 months after the employment ends, i.e., the statute of limitations for bringing an employment standards claim (under Sec. 2-89 of the Sask Employment Act).
Good Q and I hope I did a good job answering it. Glenn
