Agency Worker Detriment Letter: Free Template and What to Include

If you need to challenge removal from placement for asserting AWR rights, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong agency worker detriment letter should include.

What this letter needs to cover

• State that detriment for asserting statutory rights is unlawful
• Reference the specific AWR right asserted
• Request reinstatement to the assignment or written explanation
• State intention to pursue tribunal claim if matter not resolved

Your protection as an agency worker

Under the Agency Workers Regulations 2010, you're protected from being subjected to a detriment — including being removed from a placement — specifically because you've asserted your rights under those regulations. If a hirer or agency ends your placement shortly after you raise a legitimate rights query, the timing itself can be significant evidence that the two are connected.

What to include before you send it

• A clear timeline showing what right you asserted and when, followed by what detrimental action occurred
• Reference to your protection under the Agency Workers Regulations 2010
• A request for a clear, honest explanation of the actual reason for the placement ending
• What outcome you're seeking — reinstatement to the placement, or an acknowledgement and remedy

Building a strong case

Keep any correspondence where you raised the original rights query, and note the exact date your placement ended in relation to it. A short gap between the two events doesn't prove a connection on its own, but it's an important piece of evidence alongside anything else that suggests the timing wasn't coincidental.

Frequently Asked Questions

Can the agency or the hirer be held responsible?
Potentially both, depending on who made the decision and why — the regulations can apply to either party depending on the specific circumstances of the detriment.

What if I'm still within my first 12 weeks?
Some agency worker rights apply from day one regardless of length of service, including the right not to suffer detriment for asserting those day-one rights — so this protection isn't limited to workers who've passed the 12-week qualifying period.

Dear [Name of Contact],

Subject: Detrimental treatment for asserting my rights as an agency worker

I am writing to formally complain about detrimental treatment I have suffered as an agency worker. I believe this treatment is a direct result of me asserting my rights under the [Agency Workers Regulations 2010 / in Northern Ireland: Agency Workers Regulations (Northern Ireland) 2011].

On [Date, e.g. 12 October 2026], I raised [Briefly describe the right you asserted, e.g. my right to the same basic working conditions as permanent staff after 12 weeks].

Since raising this matter, I have experienced the following detrimental treatment:
• [Detail the first detriment, e.g. My weekly hours were suddenly reduced from 37 to 15 without explanation / My assignment was ended on [date]]
• [Detail the second detriment, e.g. I was moved to a more difficult shift pattern]
• [Detail any other detrimental treatment suffered]

Under Regulation 17 of the Agency Workers Regulations 2010, agency workers have the right not to be subjected to a detriment by an agency or a hirer for asserting their rights under the Regulations.

Please explain in writing the reason for the actions above, and [reinstate me to the assignment / restore my previous hours / put this right], within [14] days. If this is not resolved, I intend to make a claim to an employment tribunal [in Northern Ireland: an industrial tribunal].

Yours sincerely,
