Like many aspects of employment law, this is dependent upon the contractual arrangement between you and your employer.
Contrary to popular belief, most employees cannot be suspended except where there is a contract or collective agreement which grants that right to the employer or where it has been established by past practice. For example, if it is widely known and accepted that your employer can and does impose suspensions, then it may be able to establish that it has the right to suspend you. Of course, it is much clearer if that is written into a contract that you both sign.
For unionized employees, it is common for the collective agreement to give employers the right to suspend employees on various grounds.
