T he most common violation is the abusive exercise by the employer of his managerial prerogatives. Since the contract of dependent employment between an employer and a employee cannot regulate exhaustively, all the terms for the provision of labour, it is at the employer’s discretion, when exercising his managerial prerogatives, to specify such, in order to ensure the appropriate organisation and operation of the business. However, the employer must exercise his managerial prerogatives fairly, within the framework of the employment contract, labour laws, collective work agreements, the company’s work regulations, the long-standing practice of the company, etc.
