What is an agency worker job assignment confirmation letter?

Agency worker job assignment confirmation letter template preview

Agency workers need clear information about the assignment they are being supplied to undertake. This confirmation provides a practical record of the role, working arrangements and requirements agreed between the hirer and agency, helping ensure that the worker knows what is expected before they start.

Confirming the assignment

The document records the position, workplace, start date, expected duration and main duties. It can be used for a new assignment or adapted when an existing agency worker moves into a different role or assignment.

Setting out working arrangements

Working hours, shift patterns, reporting arrangements, pay information and any applicable overtime or additional requirements can be recorded clearly. This gives the agency and worker a common reference point for the assignment.

Explaining workplace requirements

The confirmation can highlight site rules, required PPE, health and safety arrangements, training, supervision and other practical requirements. This is particularly useful in manufacturing, warehouse, construction and other operational environments.

Supporting consistent agency management

Keeping a written assignment record helps HR, managers and the agency understand who is working where, under what arrangements and for what period. It can also support compliance with the Agency Workers Regulations and wider employment and health and safety obligations.

Example

A manufacturing company needs additional production capacity for a three-month period and asks an employment agency to supply a Machine Operator. The agency provides a suitable worker and confirms their availability to start the following Monday.

Before the assignment begins, the company sends the agency an assignment confirmation setting out the role, working location, shift pattern, hourly rate, expected assignment duration and the manager to whom the worker will report. It also confirms that the worker must complete the company's site induction and relevant machine safety training before undertaking certain tasks.

The worker receives the relevant assignment information through the agency and understands when and where to report, what their normal hours will be and what standards are expected. The company also confirms the PPE and site requirements that apply to the role.

When the assignment is later extended by a further month, the revised end date is confirmed with the agency and the assignment records are updated. This gives the agency, worker and company a consistent record of the current arrangement.

HR considerations

UK employment law and best practice

This template is designed to support the process, but the document should be used alongside the relevant HR procedure and applied to the circumstances of the individual case.

Agency Workers Regulations

The Agency Workers Regulations 2010 provide agency workers with certain rights from the first day of an assignment and, after a qualifying period of 12 weeks in the same role with the same hirer, rights to the same basic working and employment conditions as if they had been recruited directly by the hirer. https://www.gov.uk/agency-workers

Information about the assignment

The employment agency is responsible for providing agency workers with specified information about their assignment, including details such as the type of work, location, hours, start date and expected duration. The hirer should provide the agency with accurate information to enable it to meet its obligations. https://www.gov.uk/agency-workers

Equal treatment after 12 weeks

Once an agency worker has completed the relevant 12-week qualifying period in the same role with the same hirer, they are generally entitled to the same basic working and employment conditions as a comparable direct employee. Employers and agencies should monitor assignments carefully to ensure these rights are correctly applied. https://www.acas.org.uk/agency-workers

Pay and working conditions

The assignment information should clearly identify the applicable pay and working arrangements. After the qualifying period, relevant terms such as pay, working time, rest breaks and annual leave may need to be aligned with those that would apply to a comparable direct employee. https://www.acas.org.uk/agency-workers/after-12-weeks

Health and safety

The hirer has important responsibilities for agency workers' health and safety while they are working at the organisation. Agency workers should receive appropriate information, instruction, training, supervision and any necessary personal protective equipment for the work they undertake. https://www.hse.gov.uk/workers/agency-workers.htm

Risk assessments and training

Before an agency worker starts work, the hirer should ensure that relevant workplace and task risks have been assessed and that the worker receives appropriate induction and training. This is particularly important where the assignment involves machinery, hazardous substances, workplace transport or other significant risks. https://www.hse.gov.uk/workers/employers.htm

Working time

Agency workers are protected by the Working Time Regulations, including requirements relating to working hours, rest breaks and paid annual leave. Assignment arrangements should be planned and monitored accordingly. https://www.gov.uk/maximum-weekly-working-hours

Holiday entitlement

Agency workers are entitled to paid annual leave. The statutory minimum is generally 5.6 weeks per year, although the precise calculation can depend on the worker's working pattern and assignment. https://www.gov.uk/holiday-entitlement-rights

Agency and hirer responsibilities

The agency and hirer have different responsibilities under the agency worker framework. Clear communication between the two parties is important, particularly where an assignment changes, reaches the 12-week qualifying period or involves changes to pay or working conditions. https://www.acas.org.uk/agency-workers

Best practice

The assignment confirmation should be treated as a practical working document rather than a replacement for the agency's contractual documentation. Employers should ensure that information supplied to the agency remains accurate and promptly communicate material changes to the assignment.

FAQs

Who should issue an agency worker assignment confirmation?

The employment agency will normally provide the worker with their assignment information, but the hirer should provide the agency with accurate details about the role, workplace, hours, duration, pay arrangements and relevant requirements. This template can be used by the hirer to confirm those details with the agency.

What information should an agency worker receive before starting?

The assignment should be clearly defined, including the type of work, location, expected start date and duration, hours and other relevant working arrangements. The agency worker should also receive appropriate information about workplace health and safety and site requirements.

When does an agency worker get equal treatment?

Agency workers have certain rights from the first day of their assignment. After completing 12 weeks in the same role with the same hirer, they generally qualify for equal treatment in specified basic working and employment conditions. https://www.acas.org.uk/agency-workers/after-12-weeks

Is the agency or the hirer responsible for health and safety?

The hirer has important responsibilities for the worker's health and safety while they are working on its premises or under its direction. The agency also has responsibilities, so both parties should communicate clearly about risks, training, PPE and any restrictions associated with the assignment. https://www.hse.gov.uk/workers/agency-workers.htm

What happens if the assignment changes?

If the role, working hours, location, pay arrangements or expected duration changes, the agency and worker should be informed and the assignment information updated as appropriate. Material changes should be checked against the Agency Workers Regulations and the agency's contractual arrangements.

HRDocBox templates are designed around practical UK HR processes and help employers capture the operational, pay, health and safety and assignment information needed to manage temporary workers consistently.
