You’re not legally required to advertise a job, but it’s a good idea to do so. 

Advertising a job means: 

• you’re less likely to break the law by discriminating, even if you did not intend to
• you’ll probably get a wider range of applicants who are suitable for the job

If your business has written rules (for example, a recruitment policy) in place you should follow them.

For example, your rules might say:

• whether you have to advertise a job
• where you should advertise
• who you must advertise to (for example, internal or external applicants)

If your business has written rules, they must be applied the same way for everyone.
