How to report serious abuse or exploitation at work

What serious abuse or exploitation at work could mean and how to report it for investigation.

If you think you or someone else is in immediate risk of injury, call 999 and ask for the police.

What is serious abuse at work

You’re being seriously abused or exploited at work if you believe you’re being controlled, threatened or manipulated. This could be an indicator of modern slavery.

Signs of abuse or exploitation can include: 

  • being threatened with violence or harm 

  • not being allowed to leave your workplace or accommodation 

  • not being allowed to speak to other people 

  • having your passport taken away 

  • not being allowed to get medical treatment 

  • being forced to live in accommodation provided by your employer 

  • being made to stay in unsafe or unsuitable accommodation 

  • having your wages withheld or being forced to give wages back to your employer 

  • being forced to work to pay off a debt that keeps increasing

If this does not describe your situation

You can report other problems at work, such as pay, workplace disputes and immigration issues.
