These labels are often used loosely, but in England and Wales they carry very different legal consequences, for rights, tax and liability. Crucially, the label you use does not decide status; the reality of the relationship does. Here is how the main categories differ and why it matters.
The three core employment-status categories
UK employment law recognises three main categories:
- Employee. Works under a contract of employment, usually with mutual obligations (the employer must provide work and the employee must do it), control by the employer, and personal service. Employees have the fullest rights: unfair dismissal protection (with qualifying service), redundancy pay, statutory notice, family leave, and the written statement of particulars.
- Worker. A broader category that includes employees but also others who provide personal service but are not fully employed (such as many casual and gig workers). Workers get core rights (the National Minimum Wage, paid holiday, rest breaks, and protection from unlawful deductions and discrimination) but not unfair dismissal or redundancy rights.
- Self-employed. Genuinely in business on their own account. They have few employment rights, but keep protections such as health and safety and discrimination in some contexts, and are responsible for their own tax.
"Sole trader", "independent contractor" and "freelancer" are common ways of describing the self-employed, a sole trader is simply someone self-employed trading as an individual (not through a company).
Why the distinction matters
- Rights. Employees > workers > self-employed, in terms of legal protection.
- Tax. Tax treatment depends on the tax-status analysis of the engagement, which is separate from employment-law status. In practice, employees are typically taxed through PAYE and the genuinely self-employed usually pay through Self Assessment, but whether PAYE applies to a particular engagement depends on the tax analysis, not simply on the employment-law label. Getting this wrong can mean unpaid tax and penalties.
- Liability and IP. Employers are commonly vicariously liable for employees, and in some circumstances vicarious liability can extend to relationships akin to employment. Copyright in works created by an employee in the course of employment usually belongs to the employer, but IP ownership depends on the type of right, whether it was created in the course of employment, and any contractual terms. Contractors generally own their own IP unless it is expressly assigned.
"Off-payroll" rules (IR35)
If someone provides services through their own company (a "personal service company"), the off-payroll working rules (often called IR35) can apply. These ask whether, ignoring the company, the individual would be an employee of the client. If so, employment taxes may be due. Where the client is a public authority or a medium or large private-sector business, the client is generally responsible for assessing status and deducting tax. Where the client is a small private-sector business, responsibility typically remains with the worker's intermediary or personal service company. Getting this wrong is costly.
Status is about substance, not labels
Courts and HMRC look at the real working relationship, not what the contract calls it. Key factors include: control over how, when and where the work is done; whether personal service is required or a substitute can be sent; mutuality of obligation; integration into the business; and who bears financial risk. A contract that says "self-employed" will not hold if the reality is employment.
Practical guidance
- Don't rely on labels, assess the substance of each engagement.
- Use clear, accurate contracts, but make sure working practice matches them.
- For contractors via a company, consider off-payroll (IR35) status and who is responsible.
- Take advice where status is unclear, the cost of getting it wrong (back-pay, tax, claims) is high.
Key takeaways
- The three core categories are employee, worker and self-employed, with decreasing rights in that order.
- Sole trader, contractor and freelancer are usually ways of describing the self-employed.
- Tax, rights, liability and IP all turn on status, and the reality, not the label, decides it.
- Engagements through a personal company may trigger off-payroll (IR35) rules.
