Add Comment Question: I would like to request a year's unpaid personal leave from work in Ontario. Should I disclose the reason to my employer, and if so, how much detail is necessary? If I disclose for family reasons, are they legally allowed to ask for details? My collective agreement says that the leave can be granted at the discretion of the employer. Answer: Based on the context included in your question, it sounds like you are employed in a unionized environment subject to a collective agreement. As such, the terms of your employment and the collective agreement would need to be reviewed and assessed to properly answer your question. Your union representative/steward may be a helpful resource to consult in the circumstances.
