Secondment explained: meaning, types, law and the WorldEmp model
What is secondment, how does it work and why do more organisations choose dedicated professionals as a structural extension of their team?
Secondment is a way to organise extra capacity, knowledge and continuity without immediately hiring someone directly into permanent employment. A professional works for a client organisation, while the formal employment relationship or contractual arrangement is managed through another party. In the Netherlands, this is often done through a secondment agency, also known as a detacheringsbureau.
At WorldEmp, we give secondment a digital and international form. Our professionals work remotely, but are dedicated to the client’s team. The client remains in control of the work, priorities and daily supervision. We take care of selection, guidance and continuity.
What is secondment and why did we start with it?
More than ten years ago, we saw a pattern that many organisations still recognise today. Companies want to grow, speed up projects and maintain quality, but they run into a lack of available talent. Not because there is no work to do, but because the right people are difficult to find.
Technical specialists, engineers, developers, data specialists, document controllers and project support professionals are scarce. Local recruitment often takes too long. Traditional outsourcing can feel too far removed from daily operations. A temping agency can help with short term peaks, but does not always offer the continuity needed for structural work.
That is why we started WorldEmp. Not as a project supplier, but as a way to structurally connect organisations with dedicated professionals who become part of the team. The client keeps control of the work. The professional works remotely, speaks excellent English and is selected for expertise, reliability and collaboration.
Secondment is not a quick fix. When organised well, it is a practical way to build long term capacity. This is especially relevant for companies that work internationally, run multiple projects at the same time or struggle to find enough qualified people locally.
At its core, secondment is a three party model. There is the lender, usually the secondment agency. There is the hirer, the client organisation. And there is the employee, the seconded employee. The professional works in practice for the client, but is formally connected to the lender or works within an agreed contractual structure.
This requires clear agreements. Think about role, supervision, working conditions, safety, confidentiality, data access and assignment period. When these agreements are clear, the collaboration starts to feel like an extension of the internal team.
At WorldEmp, this model is organised digitally. The professional does not travel to the office every day, but works remotely as a fixed part of your team. That makes the model scalable, international and efficient. It fits organisations that are not only looking for someone today, but want to build capacity for the years ahead.
What is secondment? What does it mean?
Secondment means that an employee or professional is temporarily or structurally assigned to another department, organisation or client. A seconded employee works in another team or company, while the formal employment or contractual relationship remains with another party.
The secondment meaning is therefore simple: making a professional available to another working environment, with clear agreements about work, responsibility and duration.
In this context, detached meaning does not mean emotionally distant. It means placed with another organisation, department or client for a defined assignment.
What are the different types of secondment?
Secondment comes in different forms. Some are temporary and local. Others are international, strategic or fully digital.
Cross departmental secondment
Cross departmental secondment means that an employee temporarily moves to another department within the same company. This can support knowledge sharing, personal development or temporary capacity needs.
For example, a data analyst may work with operations for three months to improve reporting. The employer remains the same, but the daily working environment changes for a defined period.
External secondment
External secondment means that an employee works for a different company or host employer for a certain amount of time. This is the classic model of a secondment agency. The client supervises the daily work, while the agency manages selection, guidance and often the formal employment relationship.
This model is often used when an organisation needs specialist knowledge, but cannot or does not want to hire someone directly.
International secondment
International secondment means that a professional works for an overseas office, client or partner organisation. This can happen physically on site, but also digitally.
The benefit of international secondment is access to international knowledge and capacity. At the same time, it requires clear agreements about applicable law, tax, working hours, data security and communication.
Non profit secondments
In some cases, professionals are temporarily assigned to charitable or non profit organisations. This can be valuable for knowledge transfer, leadership development and social impact.
For employees, this can be a way to gain experience in a different context. For organisations, it can provide temporary access to knowledge that is not available internally.
Client secondment
Client secondment means that a professional works directly within a client organisation for a specified period. This can be useful for the work itself, but also for building the relationship between client and supplier.
The professional learns the client’s processes, systems and culture. This creates stronger collaboration and more mutual understanding.
Digital secondment, the WorldEmp model
Digital secondment is the form in which WorldEmp specialises. The professional works remotely, but is dedicated to your organisation. No loose outsourcing. No anonymous capacity. No project delivered at a distance.
You gain an extra colleague, digitally. The professional joins meetings, works in your systems, follows your priorities and is supervised by your team.
This makes digital secondment suitable for roles such as:
- Engineers and designers
- Developers and data specialists
- Document controllers
- Planners and work preparers
- Project support and technical administration
The model works especially well when organisations need structural extra capacity and do not want to start again and again with short term hiring.
Working through a secondment agency, what is that like?
Working through a secondment agency means that three interests need to be connected well. The client wants quality, speed and reliability. The professional wants clarity, development and respect. The agency must make sure both sides are a good fit.
A good secondment agency does more than forward CVs. It looks at technical experience, communication, availability, work attitude and cultural fit.
At WorldEmp, this is built around five values:
- People centred collaboration
- Professional reliability
- International connection
- Innovative solutions
- Acting instead of waiting
These values matter in practice. A remote professional must not only be technically strong. He or she must also communicate clearly, take responsibility and fit the way the client works.
That is why we invest time in selection, onboarding and guidance. The collaboration must be clear from the start. Who supervises the work? Which systems are used? How often do meetings take place? What results are expected? How is progress discussed?
The stronger this foundation is, the faster a professional becomes part of the team.
What does seconding mean for the agency?
For a secondment agency, seconding personnel means taking responsibility for the quality of the match and the agreements around it. The agency must ensure careful selection, clear expectations, correct registration, transparent agreements and guidance during the collaboration.
In the three party model, the agency is the lender. The client is the hirer. The professional is the employee or specialist performing the work.
In the Netherlands, the Waadi, the Workers Allocation by Intermediaries Act, plays an important role. This law applies to parties that make workers available to another organisation. Dutch government information explains that companies hiring staff through secondment must deal with Waadi rules for hiring and lending personnel.
A secondment agency therefore needs to be more than commercially effective. It must also handle compliance, working conditions and transparency carefully.
What does seconding mean for the employee?
For the employee, secondment means working in a professional environment, often with variety and development opportunities. The employee gains experience at a client organisation, learns new systems and builds expertise.
At the same time, secondment requires independence. Especially in digital secondment, the professional must communicate clearly, keep agreements and actively become part of the team.
Good guidance is therefore important. Think about career guidance, personal development, feedback moments and clear agreements about working hours, hybrid work or remote work, reporting and expectations.
For many professionals, digital secondment is attractive because they can work internationally without relocating. They gain access to professional clients, challenging work and long term collaboration, while continuing to live in their own environment.
Benefits of secondment for companies
The main benefit of secondment for companies is clear: extra capacity without a long local recruitment process. This is valuable when projects continue, deadlines are approaching and internal teams are already under pressure.
Secondment helps companies with:
- Scaling faster in a scarce labour market
- More continuity than short term temporary hiring
- Access to specialist knowledge
- Less pressure on permanent teams
- Better predictability in planning and capacity
At WorldEmp, secondment is not about outsourcing projects. The client keeps control. The professional works under the supervision of the client.
That distinction matters. Many organisations do not want to lose control over their processes, data or quality. They are not looking for a supplier that takes over the work. They are looking for people who structurally work alongside them. That is exactly where digital secondment adds value.
Benefits of secondment for employees
For employees, secondment offers access to new knowledge, international clients and professional development. They learn to work in different environments and build experience with various systems, processes and teams.
Secondment can also create clarity. A professional knows which client they work for, what the role involves and which agreements apply. Especially in longer assignments, there is room to become a real part of the team.
With digital secondment, there is an extra benefit. The professional can work internationally without physical relocation. That makes the model more human and more sustainable. Talent gains more opportunity. Organisations gain access to a broader labour market.
What is the law around secondment in the Netherlands?
In the Netherlands, secondment often falls under rules for making workers available to another organisation. The most important law is the Waadi, the Workers Allocation by Intermediaries Act.
The Waadi covers registration, equal treatment and the non obstruction rule. A party that makes workers available must be correctly registered. Business.gov.nl states that a hirer must check whether the lender is registered in the KVK Business Register and must ensure equal working conditions for hired and salaried employees.
This is often referred to as equal pay and equal working conditions. The principle means that a seconded employee should receive employment conditions that are aligned with comparable employees at the hirer.
The KVK registration check, also called the Waadi check, is therefore important. KVK explains that the Waadi aims to protect workers and that organisations can use the Waadi check to see whether a company complies with the registration requirement.
The belemmeringsverbod, or non obstruction rule, is also relevant. In simple terms, the lender may not prevent a seconded employee from entering into direct employment with the hirer after the assignment period, subject to the applicable legal conditions.
Other topics can also be relevant, such as payroll tax liability, collective labour agreement provisions, the Dutch Working Hours Act, travel allowance, remote work or hybrid work, and secondary benefits such as a lease car in local agency models. The exact application depends on the structure, country, role and agreement between the parties.
The legal landscape is also changing. The Dutch government states that the Wtta, the Dutch Admission for the Provision of Workers Act, will enter into force on 1 January 2027 and will introduce stricter rules for lenders of personnel.
That makes careful organisation important. Not only for the secondment agency, but also for the client working with that agency.
Cost of secondment
The cost of secondment depends on the role, experience level, availability, contract duration, location and guidance. In local secondment models, the rate may include margin, employer costs, travel allowance, a lease car, payroll tax liability and collective labour agreement obligations.
With digital secondment, it is better to look beyond the hourly rate. The real question is the total value of structural capacity. Think about fewer delays, less pressure on senior employees, better continuity and less time lost by constantly onboarding new short term hires.
This topic deserves a separate article about contract and money. For this page, the key question is simple: what does the professional cost, and what does it cost when the work is not done?
Secondment contract and secondment agreement
A good secondment contract or secondment agreement makes expectations concrete. It prevents misunderstandings and protects all parties.
Important elements include:
- Role, tasks and responsibilities
- Assignment period and notice period
- Rate, invoicing and costs
- Confidentiality, data and security
- Supervision, working hours and reporting
Often, there is also an assignment confirmation or placement agreement. In international or digital secondment, additional agreements are needed about system access, data security, intellectual property, compliance and communication.
A secondment letter to the employee usually describes the assignment, duration, role, reporting line, remote working arrangement and relevant employment conditions.
WorldEmp as an all round secondment partner
WorldEmp is not a traditional temping agency and not a party that takes over projects. We provide dedicated remote professionals who strengthen your team.
That means you keep control of the work. Your organisation determines priorities, workflow, planning and quality. The professional works as part of your team.
We support selection, international connection, onboarding, guidance and continuity. This creates a model that goes further than short term hiring, while remaining more flexible than fully local recruitment.
WorldEmp is relevant for organisations that need structural capacity in roles such as engineering, software development, data, document control, planning, work preparation and project support.
The strength lies in the combination of people, process and international access to talent. Not searching harder in the same scarce market, but organising capacity smarter.
