This guide is for founders, COOs and heads of engineering or finance at UK and UAE companies who have heard both terms used, sometimes interchangeably, by a partner, a recruiter or a provider, and want to know which one they are actually being offered.
What a secondment actually is
A secondment is the temporary assignment of an employee from their own employer to work at, or for, a different organisation, while the original employer remains their legal employer throughout. The seconded person typically keeps their salary and employment rights from the organisation that actually employs them, works under the day-to-day direction of the host organisation for the length of the assignment, and returns to their original role and employer once it ends. Because nothing about the underlying employment relationship changes, a secondment is generally set up by agreement between the two organisations and the employee, rather than by hiring anyone new.
Why businesses use it
Secondments show up most often between organisations that already have a relationship: a joint venture where each partner contributes staff, a group of companies moving someone between divisions or countries, a client and a supplier exchanging expertise for a defined project, or a business entering a new market by placing one of its own people inside a local partner's operation rather than opening its own entity there first. The common thread is that the seconding organisation is lending a known, trusted employee, not acquiring a new one, and it expects that person back.
What is normally written down
Because the employee's own employer stays on the hook for them throughout, a secondment agreement typically sets out the length of the assignment, who directs the person's day-to-day work while seconded, what happens to pay and benefits, and the terms on which the person returns to their original employer, since the return is usually the point of the arrangement rather than an afterthought. None of this is a substitute for advice on a specific arrangement. Secondment law and practice vary by jurisdiction, and this guide describes the general shape of the concept rather than the rules of any one country.
What staff augmentation actually is
Staff augmentation starts from a different premise: you do not have anyone suitable to lend, because the person does not work for you yet. The provider sources, screens and places a professional with your team, and for the duration of the engagement you direct their work exactly as you would an internal hire: you run the standups, set the priorities and review the output. For Outstaff Solutions specifically, that professional is legally employed through the company's own registered entity in the United Kingdom, the UAE or Pakistan, so the client does not need an entity of its own to bring the person on. The professional was never your employee before the engagement, and, unlike a secondment, there is no home role for them to return to at your company when it ends, because they were never on your payroll in the first place.
The real difference: whose employee is it, and why that changes everything else
Strip away the surface similarity and one question sorts the two models cleanly: is this a person your organisation already employs, temporarily working somewhere else, or a person a provider employs, working for you? Everything else, who is liable if something goes wrong, who pays the person, what happens at the end of the arrangement, follows from that single fact.
Under a secondment, your organisation (or the partner organisation, if the secondment runs the other way) remains the employer throughout, carries the ongoing employment obligations, and gets the person back once the assignment ends. It works well precisely because both sides already have a reason to trust the arrangement: a partnership, a group structure, a joint venture. It is not really a way to buy capacity from the open market; it is a way to move capacity you already have.
Under staff augmentation, the provider is the employer from day one, for as long as the engagement runs, and there is no "returning" the person anywhere, because they were sourced for this placement rather than lent from an existing role. It is built for exactly the situation a secondment cannot solve: you need capacity you do not currently have anywhere in your organisation, and there is no sister company, partner or joint-venture counterpart with a spare, trusted employee to send you.
Staff augmentation vs secondment, side by side
| Secondment | Staff augmentation |
|---|
| Who is the legal employer | The person's original employer, throughout | The provider, through its own registered entity |
| Where the person comes from | Already employed by you or a partner organisation | Sourced and screened by the provider for this placement |
| What happens at the end | The person returns to their original role and employer | The engagement ends; there is no "home role" to return to |
| Typical relationship between the parties | Two organisations with an existing relationship: a partner, a group company, a joint venture | A commercial engagement with an external provider |
| Best suited to | Moving a known, trusted employee somewhere else temporarily | Adding capacity your organisation does not currently have anywhere |
| Who directs day-to-day work | The host organisation, for the length of the assignment | The client, exactly as with an internal hire |
| How it starts | Agreement between the two organisations and the employee | Sourcing, screening and placement by the provider |
When secondment is the right tool
Secondment fits situations where the capacity already exists somewhere in your organisation or your network, and the problem is getting it to the right place temporarily rather than finding it in the first place. A joint venture where each partner contributes named staff, a group of companies moving someone from a UK office to help stand up a new function elsewhere, or a client and a long-standing supplier exchanging a specialist for a defined project are all secondment situations. What they share is an existing relationship of trust between two organisations, and an employee who is expected to go back to where they came from.
When staff augmentation is the right tool
Staff augmentation fits the far more common situation: you need a capability your organisation does not have anywhere, and there is no partner or sister company positioned to lend you a trusted employee for it. This is most of what offshore engineering, design and AI hiring actually is, and it applies just as much to outsourced finance and back-office roles. There is no employee anywhere in your group to second, so the question is not who to move, it is who to bring in, and that is a sourcing and employment problem a staff augmentation provider is built to solve. See how it works for what that sourcing and placement process actually involves, and staff augmentation vs in-house hiring for how it compares with recruiting the role permanently yourself.
Can the two work together?
Often, and in a specific pattern worth naming: a company seconds one of its own trusted people, a manager, a technical lead, someone who already knows the product, to direct an augmented team it has separately engaged offshore. The secondment supplies the direction and institutional knowledge; the staff augmentation engagement supplies the additional hands. Neither model is doing the other's job. The seconded employee is still your employee, temporarily focused on standing up and directing the new capacity; the augmented professionals are the provider's employees, doing the work under that direction. Treating them as substitutes for each other is the mistake; treating them as two tools that solve different halves of the same problem usually is not.
A short way to decide
Ask one question first: is there a specific employee, already on someone's payroll, who could plausibly do this and go back to their original role afterwards? If yes, and the relationship between the two organisations already supports lending that person, a secondment is worth structuring properly, with the assignment length, direction and return terms agreed in writing before it starts. If the honest answer is no, because the capability simply does not exist anywhere in your organisation or your partner network yet, secondment is not the model, whatever a conversation happens to call it, and the actual question is a sourcing one: talk to us about the specific role, and we will tell you plainly whether staff augmentation fits it.
Frequently asked questions
Is a secondment the same as staff augmentation?
No. A secondment moves an employee who already works for one organisation to work temporarily at another, with the original employer remaining the legal employer throughout. Staff augmentation places a professional sourced and employed by a provider with your team; that person was never your employee and there is no original role for them to return to.
Who is the legal employer during a secondment?
The person's original employer remains their legal employer for the duration of a secondment. They typically keep their salary and employment rights from that employer while working under the host organisation's day-to-day direction.
Can we second one of our own people to manage an augmented offshore team?
Yes, and this is a common and sensible combination. A secondment supplies direction and institutional knowledge from someone you already trust; a staff augmentation engagement supplies the additional capacity that person then directs. The two arrangements can run side by side without one replacing the other.
Does a secondment need a written agreement?
General practice, not a claim about any specific jurisdiction's law: secondments are typically documented with an agreement covering the length of the assignment, who directs the work, what happens to pay and benefits, and the terms of the employee's return. This guide describes the general shape of the concept; get advice specific to your situation and jurisdiction before agreeing one.
Where to start
If you already have a trusted employee and a partner organisation willing to host them, a properly documented secondment is worth setting up on its own terms. If the capability you need does not exist anywhere in your organisation yet, that is a different problem, and it is the one staff augmentation is built to solve. Talk to us about the role in front of you and we will tell you which one actually fits it.
