An employer may employ you on a trial period of up to 90 calendar days. Here are some things you should keep in mind about trial periods:
You and your employer may also agree to an initial probationary period when you start work. This must be recorded in writing in the employment agreement.
Probation periods are different to trial periods. During the probation period your employer still needs to follow a fair disciplinary or dismissal procedure (like telling you what the issues are, giving you time to seek advice, and giving you an opportunity to improve). The employer can’t simply tell you to leave at the end of the probation period. If you have been working on a probation period you may raise a personal grievance on the grounds of unjustified dismissal, if you think the employer did not have good reason to dismiss you.
