Inherent Requirements of the Job: When Can Employers Justifiably Differentiate?

South African labour law provides robust protection against unfair discrimination in the workplace. Employers may generally not make employment decisions based on characteristics such as race, gender, religion, disability, age, or other protected grounds. However, these protections are not absolute. In certain circumstances, a particular characteristic, qualification, skill, or physical ability may be so fundamental to a position that it constitutes an inherent requirement of the job. Where this can be established, employers may lawfully differentiate between employees or applicants without contravening discrimination laws.

The Legislative Framework

Section 187(1)(f) of the Labour Relations Act 66 of 1995 (“LRA”) provides that a dismissal is automatically unfair if it is based on unfair discrimination on an arbitrary or listed ground. However, section 187(2)(a) creates an exception where the reason for dismissal is based on an inherent requirement of the particular job. Similarly, section 6(1) of the Employment Equity Act 55 of 1998 (“EEA”) prohibits unfair discrimination, while section 6(2)(b) provides that it is not unfair discrimination to distinguish, exclude, or prefer a person based on an inherent requirement of a job. The inherent requirements defence is therefore a narrow exception to the prohibition against workplace discrimination. Employers relying on the defence must demonstrate that the requirement is genuinely necessary for the performance of the job and not merely based on preference, convenience, or historical practice.

What Does “Inherent” Mean?

The Labour Appeal Court has consistently held that an inherent requirement must be an essential and indispensable component of the job itself. The requirement must relate directly to the nature of the work performed and the legitimate operational objectives of the employer. Put differently, the employer must demonstrate that the requirement is indispensable to the performance of the job and that removing it would undermine the legitimate operational purpose for which the position exists. A requirement will not qualify as inherent simply because it is desirable, convenient, or preferred by management.

Religious Accommodation and Operational Requirements

The interaction between religious rights and workplace requirements was considered by the Labour Appeal Court in TFD Network Africa (Pty) Ltd v Faris (2019) 40 ILJ 326 (LAC). The matter involved a Muslim employee who sought time away from work to attend Friday congregational prayers. The Court recognised that religious freedom enjoys constitutional protection and emphasised that employers should, where reasonably possible, seek to accommodate sincerely held religious beliefs and practices. In determining whether a workplace rule or requirement may justifiably limit an employee’s religious rights, the Court adopted a proportionality-based approach that balances competing constitutional and operational interests. This enquiry requires consideration of several factors, including the importance of the purpose served by the limitation, the extent of the limitation imposed on the employee’s religious rights, the relationship between the limitation and its purpose, and whether less restrictive means could achieve the same objective. Importantly, the Court made it clear that employers cannot rely merely on operational inconvenience when limiting religious practices. There must be a genuine and rational connection between the restriction imposed and the operational objective sought to be achieved. The practical question employers should ask is – “Can the employee’s religious practice be reasonably accommodated without undermining the essential functioning of the business?”

Only where accommodation would materially impair the employer’s operational requirements may limitations on religious practices be justified. A similar balancing exercise was undertaken in Sun International Management Ltd v Sayiti and Others (JA 13/23) [2024] ZALAC 52. The Labour Appeal Court confirmed that where an employer relies on section 187(2)(a) of the LRA, it bears the burden of proving that the requirement relied upon is genuinely inherent to the job. The Court emphasised that employers must demonstrate more than preference, convenience, or administrative efficiency. The requirement must be objectively necessary for the effective performance of the job. The defence is evidentiary in nature, requiring employers to present objective evidence demonstrating why the requirement is indispensable and why reasonable accommodation is not feasible in the circumstances. The judgment serves as an important reminder that employers should carefully explore reasonable accommodation measures before seeking to rely on the inherent requirements defence

Physical Fitness as an Inherent Requirement

A useful comparison can be drawn with Damons v City of Cape Town [2022] 7 BLLR 585 (CC). This case concerned a firefighter who was denied promotion because he no longer met the physical fitness requirements applicable to operational firefighters following a disabling injury. The Constitutional Court accepted that physical fitness was an inherent requirement of an operational firefighter position. The Court held that where a person cannot perform an essential requirement of the job, the inherent requirements defence may constitute a complete defence to an unfair discrimination claim. The Court accepted that the employer’s operational concerns were real and substantial. The evidence demonstrated that allowing firefighters who lacked the required physical fitness could negatively affect public safety, the safety of fellow firefighters, the employer’s ability to respond effectively to emergencies and the efficient and effective functioning of the fire service. The case illustrates a situation where the inherent requirement was directly connected to the core purpose of the job itself.

Conclusion

South African courts continue to strike a careful balance between protecting employees from unfair discrimination and recognising the legitimate operational needs of employers. The jurisprudence demonstrates that the inherent requirements defence is not a loophole that allows employers to circumvent discrimination laws. Rather, it is a narrowly construed exception designed to protect employers where a particular requirement is genuinely indispensable to the performance of a specific job. Courts will closely scrutinise whether the requirement serves a legitimate operational purpose, whether it is objectively necessary for the position in question, and whether reasonable accommodation has been adequately considered. Employers should therefore approach reliance on the defence cautiously and ensure that any differentiation is supported by objective evidence rather than assumptions, preferences, or administrative convenience. Organisations that can demonstrate a genuine operational necessity, apply the defence consistently, and meaningfully consider accommodation measures will be best positioned to justify their decisions if challenged before the CCMA, Labour Court, or other adjudicative forums.
