1. Introduction

Section 2(1)(a) of the Unfair Dismissals Act 1977 (as amended) restricts the protection of the Acts to employees with at least one year’s continuous service. This service requirement is a fundamental threshold question in every unfair dismissal complaint.

This article sets out the operation of the one-year rule, the calculation of continuous service, the categories of employee to whom the rule does not apply, and the practical implications for both employers and employees in the first year of employment.

2. Legislation and Case Law

Section 2(1) of the Unfair Dismissals Act 1977 excludes from the protection of the Act employees with less than one year’s continuous service. Continuous service is calculated in accordance with the First Schedule to the Minimum Notice and Terms of Employment Act 1973.

Critical exceptions apply. The one-year rule does not apply where the dismissal results wholly or mainly from the employee’s pregnancy, attendance for ante-natal classes, maternity leave, breastfeeding, adoptive leave, parental leave, force majeure leave, or carer’s leave. The rule also does not apply to dismissals for trade union activities (Section 6(2)(a)) or for the making of a protected disclosure (Section 6(2)(ba)).

Service is calculated up to the effective date of termination. Where the employee has been given notice, the effective date of termination is the date on which the notice expires (or, where pay in lieu is given, the date on which the employment actually ended).

Where the employee has been engaged on a series of fixed-term contracts with the same employer, the service is generally aggregated (subject to the operation of the Protection of Employees (Fixed-Term Work) Act 2003). 

3. Decision

The application of the one-year rule is generally mechanical, but a number of recurring issues arise. The first is the calculation of continuous service across multiple successive contracts. The second is the treatment of agency workers under the Protection of Employees (Temporary Agency Work) Act 2012.

The third is the application of the exceptions. Where the dismissal of an employee with less than one year’s service is alleged to result from one of the protected grounds, the WRC will examine the causation question with care. The shorter the service, the easier it may be for an employee to draw a temporal connection between the protected activity and the dismissal.

The fourth is timing. Where an employer has dismissed an employee close to the one-year mark, the WRC will scrutinise the timing of the decision. A dismissal that conveniently falls a few days short of the one-year service threshold may itself attract suspicion, particularly where the asserted reason for dismissal is weak.

An employee dismissed during the first year retains potential rights under other statutes (Payment of Wages Act, Employment Equality Acts, Minimum Notice and Terms of Employment Act) which do not generally carry the same service requirement.

4. Takeaway

The one-year service rule is the threshold question in every unfair dismissal complaint. Employees with less than one year’s service are generally excluded from the protection of the Acts, save in cases falling within the specified exceptions.

For employers, the practical implication is that the first year is a period of relative flexibility. An employer is generally free to terminate the employment of an employee in their first year without exposure to an unfair dismissal complaint. This flexibility is, however, subject to important qualifications.

Employers should be alert to the dangers of dismissals timed close to the one-year mark. A dismissal that conveniently occurs just before the one-year service threshold may attract attention and may be examined for ulterior motive.

For employees, the practical advice is to be aware of the service threshold and to consider, where dismissal is in prospect during the first year, whether any of the exceptions might apply. Practitioners should also consider claims under other employment statutes.
