The employees of a transportation company complained to management that the men's washroom was very messy, despite regular cleaning. The employer implemented a log system that monitored the use and the state of the men's washroom. After three days of monitoring, the employer concluded that the facility required attention only after it was used by a particular employee, John. The employer gave John a disciplinary letter advising him that his behaviour had to stop; otherwise, progressive disciplinary actions would be taken. John filed a complaint with the federal privacy commissioner, alleging that management had monitored his washroom visits without his consent and used the collected personal information for disciplinary purposes. Did the employer infringe PIPEDA in this situation? Explain your answer.
