A probationary or trial period should be written into all contracts of employment to ensure that the employer has an opportunity to assess the capability, reliability and suitability of a new recruit. A standard period for a probationary period would be three months.
From a legal point of view, the employee on a probationary period has the same rights as a permanent employee (see Notice Periods).
Having regular reviews during the probationary period helps to ensure that you give your new recruit all necessary support and every opportunity to know about and fix any problems or concerns you might have. This gives you both the best chance to make this succeed and make the most of your employee’s potential.
