An employer decides to dismiss an employee without notice and without legal cause. Subsequent to the dismissal, in reviewing the employee’s work, the employer discovers a number of errors which, if known at the time, would have been sufficient to support a dismissal for cause. Can the employer successfully argue cause in defence of a wrongful dismissal claim? This is a question I have been asked many times by employers, as a review of a dismissed employee’s work after dismissal often reveals significant errors or, in some cases, outright dishonesty.
