Someone placed by an employment agency to work shifts for a business, without being directly employed by that business. Agency workers still have rights under laws like the Employment (Allocation of Tips) Act 2023, even though their employment contract sits with the agency.
In practice
A hospitality venue can bring in staff through an agency for a busy shift. Those workers are still owed a fair share of tips under the law, even though their contract is with the agency, not the venue.
