Casual workers
In the UK, casual worker is an everyday term for people engaged as needed or on irregular hours, but the legal question is whether they are an employee, a worker, or self-employed.
Casual workers are people engaged as needed or on irregular hours rather than on a fixed full-time pattern.
In the UK, that phrase is common in everyday workplace language, but it is not the key legal category on its own. The real status question is whether the person is an employee, a worker, or self-employed, because those categories drive rights and obligations. A hospitality venue may describe a flexible pool as casual workers while still needing to work out, in law, which status each person actually has.
The pattern is common in events, hospitality, retail, care, and agency staffing, where demand changes from week to week. In practice, the attraction is flexibility for both sides, but that flexibility does not remove the need to classify the relationship correctly.
Different elsewhere: in Australia, casual employment is a more specific legal status and usually comes with casual loading. In the US, casual worker is often described more loosely as as-needed labor with fewer benefits, without the UK’s separate worker-status framework.
