Probationary period myths busted

You’ve been offered a new job, but your new Employer has made you a conditional job offer that includes a probationary period for the first few months of your employment. What does that mean?

(Article updated for 2013)

Probationary periods are often for the first 3 or 6 months of your new job and are used by your Employer to assess your performance and conduct during your early stages of employment, to make sure they are happy with your work.

However, probationary periods have no legal basis, so what do they actually mean? Here we give you the basic facts:

  • Your Employment starts from your original start date, not from the date at the end of your probationary period (when you are ‘confirmed’ in the job).

  • This means that your length of service, which is essential in determining your eligibility for statutory employment rights, starts from your original start date and is not affected by the probationary period.

If your Employer is not satisfied with your performance or conduct during your probationary period:

  • They may have the option to extend the probationary period if this is written into your contract (but again this does not affect your original start date) or

Your Employer can dismiss you legally if they are unhappy with your performance or conduct if:

  • They follow correct disciplinary procedures (your Employer may also have a separate probationary period policy which outlines their procedures to end your employment) and

  • However, your Employer does not have to wait until the end of your probationary period to dismiss you.

If your Employer does not follow a disciplinary procedure to dismiss you, and your Employers disciplinary procedure is contractual, then they may be in breach of contract.

If you believe that your dismissal is unfair and you have 2 years service with your Employer (from your original start date, not from the end of your probationary period) you can bring a claim for unfair dismissal to an Employment Tribunal. You can bring a claim for discrimination to an Employment Tribunal at any point in your employment, from day 1, you do not need to have 2 years service if you believe you have been discriminated against.

An important Employment Appeal Tribunal decision in 2007 (Przybylska v Modus Telecom Limited) found that where there is an express contractual right for the Employer to extend (or not) the probationary period, within the initial probationary period timescale, and the Employer does not do this they lose their right to extend the probation. Therefore, the probationary period is completed by ‘default’ and the employee is therefore entitled to the notice periods that apply after the probationary period (which are usually longer than those during the probationary period).

The brief details of the case are: Miss Przybylska was employed on a 3 month probationary basis from 3 October 2005. During this probation her employment could be terminated with a week’s notice and Modus reserved the right to extend the probationary period. Miss Przybylska was on holiday when her probationary period expired on 2nd January 2006 and Modus had not extended her probationary period when her holiday began. At the end of January 2006 she was dismissed with one weeks’s pay in lieu of notice.

She complained of breach of contract to the Employment Tribunal (she said she should have been paid 3 months notice after completion of her probationary period). The ET said it was reasonable for the probationary period to continue until she had received an indication of whether she had successfully completed it or not. The EAT disagreed, saying that the assessment should have taken place during the probationary period and Modus should have foreseen she would have been on holiday at its end; they could have extended the probationary period if they had not been able to complete her assessment before the holiday. The EAT felt it was not necessary to imply a term which automatically extended the probationary period.
