How To Create A Secondment Policy: Key Clauses, Risks And Best Practices

Secondments can be a great way to build capability in your team without committing to a permanent change. You might second an employee into a new role to cover parental leave, support a major project, test a restructure, or share talent across related entities in your group.

But a secondment is still an employment arrangement, which means it needs clear boundaries. Without a solid secondment policy, it’s easy for things to get messy: who manages the employee day-to-day, whose policies apply, what happens if the secondment ends early, and what you do with confidential information once they move back.

This is where a well-drafted secondment policy helps. It gives you a consistent framework, reduces disputes, and makes sure your business stays compliant while remaining flexible.

Below, we’ll break down what a secondment policy should cover, the clauses that matter most, the legal and commercial risks to watch for, and the best practices we recommend for Australian small businesses.

What Is A Secondment Policy (And When Do You Need One)?

A secondment policy is an internal workplace policy that sets out how your business will manage temporary placements of employees into another role, team, location, or sometimes another organisation (for example, a related entity or a business partner).

In practical terms, a secondment policy should help you answer questions like:

• When can a secondment be offered (and who approves it)?
• How long can it last, and can it be extended?
• Does the employee’s pay or hours change?
• Who supervises performance and manages day-to-day work?
• What happens at the end (or if it ends early)?

You generally don’t legally need a secondment policy in every business. However, if you ever move staff between roles or entities, a written framework is a big risk-reducer. It also helps you be consistent and fair, particularly if multiple employees are asking for temporary opportunities.

Common Secondment Scenarios For Small Businesses

• Internal role coverage: an employee covers another employee’s leave (e.g. parental leave, long service leave, extended sick leave).
• Project-based secondments: you assign someone to a temporary project team, then they return to their normal position.
• Cross-entity secondments: you move staff between related companies (for example, operating company to holding company, or between subsidiaries).
• External secondments: you second an employee to a client, supplier, joint venture partner, or industry body for a defined period.

If you’re moving people within a group of companies, it’s also worth thinking about the legal mechanics of moving staff between entities. Depending on the structure, it might resemble transferring employees within group companies rather than a simple internal secondment.

Key Clauses To Include In A Secondment Policy

Your secondment policy should be clear enough that a manager can apply it, and specific enough that employees understand what they are agreeing to.

In many cases, the policy works best when paired with a secondment letter (or secondment agreement) issued for each placement. The policy sets the rules of the system; the letter sets the details of that individual secondment.

1) Purpose And Scope

Start by defining what you mean by “secondment” and what arrangements the policy covers.

• Is it only for internal role changes, or does it include placements to other entities?
• Does it apply to full-time, part-time and casual employees?
• Does it cover temporary acting roles and higher duties?

Being clear about scope avoids debates later about whether something is a “secondment” or just “helping out for a bit”.

2) Eligibility And Approval Process

Set out who can approve secondments and what criteria you’ll consider. For example:

• business need and operational coverage
• employee suitability (skills, experience, performance)
• cost impacts
• conflicts of interest
• work health and safety considerations (including training needs)

This is also where you can specify that a secondment is not an entitlement and may be declined based on operational requirements.

3) Term, Extensions And Review Points

Secondments work best when they are genuinely temporary. Your policy should address:

• how long secondments can run (e.g. 3, 6, 12 months)
• whether extensions are allowed (and how many)
• check-in points (e.g. 4-week and 3-month reviews)
• what happens if the employee’s substantive role changes during the secondment (e.g. restructure)

Clear timeframes protect you from “temporary” arrangements quietly becoming permanent without proper documentation.

4) Role, Duties, Location And Reporting Lines

This part is often overlooked, but it’s where many disputes begin.

Your secondment policy should make it clear that each secondment will specify:

• the seconded role title and key duties
• work location (including remote/hybrid expectations)
• who the employee reports to day-to-day
• who remains responsible for HR decisions (payroll, leave approvals, discipline)

If an employee’s duties are changing significantly, you’ll want to handle that carefully and consistently with your existing employment arrangements, including what’s written in your Employment Contract (or other engagement documents).

5) Pay, Allowances, Hours And Benefits

A secondment may involve:

• higher duties (and higher pay)
• different hours or shift patterns
• travel requirements
• different tools or allowances (e.g. vehicle allowance)

Your policy should state the principle you’ll apply, such as:

• whether pay changes are temporary or permanent
• whether allowances apply based on the seconded role
• how overtime/TOIL is handled

If your workforce includes award-covered employees, you’ll also want to check the relevant modern award (or enterprise agreement) for higher duties rules, minimum engagements, penalty rates, and consultation requirements.

6) Leave And Entitlements During Secondment

Secondments can create administrative confusion around leave, especially for longer placements.

Your policy should clarify:

• who approves leave during the secondment
• how leave accrues (usually unchanged)
• how public holidays apply if the location or roster changes
• what happens if the employee takes extended leave during the secondment

Where leave becomes contentious, disputes often arise because expectations weren’t set early. A policy helps align everyone.

7) Performance, Conduct And Workplace Policies

Even if an employee is working in another team (or at another organisation), you need to be clear about which workplace policies apply and who handles performance issues.

Most businesses set a baseline that:

• your Code of Conduct and key workplace policies always apply, even during secondment
• the host manager provides day-to-day feedback
• formal performance management remains with the home employer (or is shared under a defined process)

If you use workplace surveillance, CCTV, or call recording, be careful: the rules differ across Australian states and territories, and can also depend on notice/consent and the specific circumstances. If this is relevant to your business, it can help to sanity-check your approach against the rules in recording laws in Australia and ensure your policy position matches your actual practices.

8) Confidentiality, Privacy And Data Security

Secondments often involve access to sensitive information: customer lists, pricing, strategy, product plans, or staff data. Your policy should:

• remind employees of confidentiality obligations
• limit access to information on a “need to know” basis
• cover return or deletion of business information at the end of the secondment
• set expectations for use of devices, passwords and systems

If your secondment involves sharing personal information with another entity (for example, sending HR records to a host organisation), privacy compliance matters. Many businesses support this with a clear Privacy Policy and an internal process for handling employee data disclosures.

9) Ending The Secondment (Including Early Termination)

This is one of the most important parts of a secondment policy because it prevents surprises.

Your policy should cover:

• what triggers the end (end date, completion of project, return of incumbent employee)
• whether you can end the secondment early, and on what grounds (e.g. business needs, performance concerns, misconduct, capability issues)
• how much notice you’ll give (if any) and how the transition works
• what role the employee returns to (typically their substantive role or a comparable role)

Be careful not to promise outcomes you can’t guarantee. If there is a genuine possibility that the substantive role may not exist at the end (for example, due to a restructure), you’ll want this handled with tailored legal advice rather than relying on a generic policy statement.

Legal And Commercial Risks To Watch Out For

A good secondment policy isn’t just an HR document. It’s a risk management tool. Here are the big issues we see small businesses run into.

Confusion About Who The Employer Is

For internal secondments, this is usually straightforward.

But for secondments to another entity (especially external host organisations), confusion can arise around:

• who issues lawful directions
• who manages WHS obligations
• who is responsible for payroll, superannuation and insurance
• who handles complaints, misconduct investigations, or termination

If you’re seconding someone into another organisation, your secondment policy should clearly set out the intended arrangement (for example, whether they remain employed by you while working under the host’s day-to-day supervision, or whether another structure is being used). Because “who the employer is” can depend on the facts and documentation, it’s important that each external secondment is properly documented and roles/responsibilities are clear.

Unintended Variation Of The Employment Contract

A secondment often changes duties, reporting lines, location, and sometimes pay. If handled poorly, it can look like you’ve permanently changed the employee’s contract terms without proper agreement.

This is why it’s important that secondments are documented, time-limited, and consistent with the employee’s existing engagement terms.

Modern Award / Enterprise Agreement Compliance

If the employee is covered by an award or enterprise agreement, a secondment can trigger additional compliance requirements, such as:

• higher duties classifications and minimum rates
• rostering and breaks
• allowances (travel, tools, uniform)
• consultation obligations for major change

A policy helps you standardise the checks you’ll do before approving a secondment, rather than discovering problems after the fact.

Confidentiality And IP Leakage

Secondments can create real risk around confidential information, trade secrets, and intellectual property (IP), particularly where the host is external.

Your policy should work alongside your contracts and internal controls to prevent:

• employees sharing sensitive info “because the host asked for it”
• documents being stored on host systems without safeguards
• unclear ownership of work product created during the secondment

Depending on the role, you may also need a separate agreement with the host organisation addressing confidentiality and IP ownership, not just an internal policy.

Work Health And Safety (WHS) And Duty Of Care

If an employee is working at a host site, safety responsibilities can overlap. Your business may still owe duties to your employee even where another organisation controls the workplace.

A secondment policy can help by requiring:

• a safety induction at the host location
• confirmation of supervision and incident reporting procedures
• clarity on what to do if the employee believes work is unsafe

Best Practices For Implementing A Secondment Policy

Even the best secondment policy won’t help if it’s not used consistently. These are the practical steps that make the policy actually work day-to-day.

Create A Simple Secondment Approval Checklist

Small businesses move fast, so you’ll want a quick checklist that sits behind the policy. This can include:

• confirmation of the secondment purpose and timeframe
• pay and classification check (award/EBA if applicable)
• WHS induction plan
• system access and confidentiality controls
• draft secondment letter prepared and signed

This is particularly helpful if you have multiple managers who may run secondments differently unless you standardise the process.

Use A Written Secondment Letter Every Time

A policy sets general rules, but a letter sets the specifics. Ideally, each secondment letter should confirm:

• start date and end date
• the seconded position and duties
• reporting line and work location
• temporary pay changes and any allowances
• how the secondment ends and what role the employee returns to

If the secondment changes key terms, it should be signed by the employee to avoid later disputes about what was agreed.

Align Your Secondment Policy With Your Other Workplace Documents

A common issue is having policies that contradict contracts or other internal documents.

Before rolling out a secondment policy, check it aligns with:

• employment contracts and contractor agreements
• your staff handbook and workplace policies
• position descriptions
• confidentiality and IP clauses

If you’re updating multiple documents at once, a broader review can help. Many businesses do this as part of a periodic Legal Health Check to make sure documents still reflect how the business actually operates.

Be Clear About “Acting” Roles And Career Progression

Secondments are often used as development opportunities, which can be a big positive for retention. But it’s important to manage expectations.

Your secondment policy should clearly state whether a secondment:

• is a trial for a future permanent role (sometimes it is, often it isn’t)
• changes the employee’s substantive position (usually it should not)
• affects eligibility for promotion or pay reviews

This helps you avoid misunderstandings like “I’ve been doing the role for six months, so it’s mine now”.

Plan The Return Early (Not At The Last Minute)

The end of a secondment is where operational friction often appears. A good practice is to schedule a return-planning conversation well before the end date (for example, at the halfway point and again 4 weeks before the end).

This gives you time to:

• confirm whether the secondment will end, extend, or transition into something else
• manage handover and training
• prepare the employee’s original team for their return

What Other Documents Should Support Your Secondment Policy?

A secondment policy is most effective when it sits within a broader legal and HR framework. Depending on your business, you may also want:

• Employment contracts: so your baseline terms are clear before you temporarily change duties or reporting lines (often supported by an Employment Contract (FT/PT) for permanent staff).
• Workplace policies: covering conduct, confidentiality, IT use, and performance management so expectations remain consistent across teams and locations.
• Privacy documentation: particularly if employee information is shared across entities or you manage employee records in multiple systems, supported by a Privacy Policy.
• IP and confidentiality terms: especially if the employee will build new material or access sensitive business information during the secondment.
• Intercompany documentation: if staff are seconded across your group, you may need a clear agreement between the entities (and sometimes it’s paired with arrangements like an Intercompany IP Licence where IP use is shared across entities).

Not every business will need all of these, but it’s worth setting things up properly if secondments are a regular part of how you operate.

Key Takeaways

• A clear secondment policy helps you move staff temporarily while reducing disputes about supervision, pay, entitlements, and what happens at the end.
• Your policy should cover approvals, term and extensions, reporting lines, pay and allowances, leave, performance expectations, confidentiality, and end-of-secondment processes.
• Key risks include confusion about who the employer is (especially across entities), unintended contract changes, award compliance issues, and confidentiality/IP leakage.
• Best practice is to pair your policy with a written secondment letter for each secondment, plus a simple internal checklist managers can follow.
• Secondments work best when they align with your employment contracts, workplace policies, and privacy/confidentiality controls.
