Sometimes employers include 'exclusivity clauses' in contracts. These clauses are to stop a worker from either:
- working for another employer
- working for another employer without consent
If someone's on a zero-hours contract
By law (Employment Rights Act 1996), if someone is on a zero-hours contract, their employer must not:
- try to stop them working for another employer by putting an exclusivity clause in their contract
- treat them less favourably if they also work for another employer
- dismiss them for working for more than one employer – this could be an unfair dismissal
If someone earns below the lower earnings limit
The law banning the use of exclusivity clauses also applies when someone's weekly income is below or equivalent to the lower earnings limit (LEL).
The government sets the lower earnings limit each tax year. The lower earnings limit for 6 April 2024 to 5 April 2025 is £123 per week. From 6 April 2025, the lower earnings limit will be £125 per week.
If you have any questions about the lower earnings limit, contact HM Revenue and Customs (HMRC).
If an employer includes an exclusivity clause that's against the law
The law banning the use of exclusivity clauses still applies even if the employer:
- has included an exclusivity clause in the contract
- says a worker has broken their contract by working for another employer
This is because an employer cannot enforce a clause that is against the law.
If someone feels that their employer is including a clause that is against the law, it's a good idea to raise this informally first. They can do this by talking with their employer.
