Employee, worker or self-employed?
Your employment status dictates your rights and entitlements, and determines an employer's responsibilities.
Confusions can arise because employment status can be different under tax law and employment law. It is possible that you may be regarded as self-employed by the HMRC, but as a worker or an employee by an employment tribunal (industrial tribunal in Northern Ireland).
At gov.uk you can read more about working out someone's employment status, i.e. worker, employee or self-employed. For the purpose of tax, see the HM Revenue and Customs (HMRC) Employment Status Indicator (ESI) tool.
If you are self-employed, your rights and responsibilities are set out in the contract for services you have with the other party. A self-employed worker does not have the same employment rights and responsibilities as an employee.
