Employee Status and Rights
The status of an employee, once confirmed in service, becomes that of a permanent employee occupying a post and pay personal to him. This status cannot simply be taken away. In certain organizations, an employee, upon promotion, may be put on probation (such as a worker promoted to a supervisory post or a supervisor being promoted to an executive post) or on a trial period. However, during this period, the employee still retains rights over the substantive post he occupied before such an event. If the employee is found unfit for the new post, he can only be reverted back to the substantive post. Therefore, the rights an employee has earned on the permanent post held earlier cannot be merely taken away by making him a temporary employee.
