Whether or not a company implements a probationary period as part of any new employment agreement is completely at their discretion. If the conditions set within the probationary period do not breach any labor laws applicable to the country it is undertaken in, then probation periods are completely legal and allowed. It is important that both parties have a clear understanding of what is required of them during this period, what to expect when the probationary period ends, and the methods that will be used to assess their competency in the role.
