Webb v EMO Air Cargo (UK) Ltd (No 2) (1994) C-32/93 is a UK labour law and EU labour law case, concerning discrimination against a pregnant woman. It held that no comparator (for instance to a sick man) is necessary to establish discrimination against a pregnant woman. It was unusual in that Carol Louise Webb, the applicant, was represented throughout by a community law centre, the Hillingdon Legal Resource Centre (HLRC), later renamed the Hillingdon Law Centre, the only time that a British law centre case went to the European Court of Justice. The law centre's in-house barrister Michael Shrimpton argued the case before the Industrial Tribunal at London North in February 1988. He was also junior counsel to the late John Melville Williams QC in the Employment Appeal Tribunal and, by then in private practice, appeared at the compensation hearing in 1999. The case was one of the longest-running in British legal history.

EMO Air Cargo had an employee called Mrs Stewart who had taken maternity leave. Miss Webb was hired to replace Mrs Stewart, though it was envisaged that she would stay on working after Mrs Stewart came back. Then, however, it transpired that Miss Webb was also pregnant and due to give birth at around the same time as Mrs Stewart. Miss Webb was dismissed. She claimed this was sex discrimination under SDA 1975 s 1(1). The employer argued she was unable to carry out the tasks for which she was recruited.

The Court of Appeal held that a sick man, who was the appropriate comparator, would have been treated similarly. The House of Lords referred to the ECJ.
