A secondment is a temporary arrangement where an employee works for another organisation, department, or country. The secondee keeps their original employment contract throughout the assignment. Secondment covers both domestic transfers and international placements. This guide explains the secondment definition, what a secondment agreement should include, and how HR managers can structure secondments compliantly across borders.
What does secondment mean?
Secondment means the temporary transfer of an employee to another organisation, role, or country. The secondee continues under their original employment contract while performing work for the host organisation. Seconding an employee typically lasts between three months and three years. The secondment definition applies equally to domestic and international assignments.
In practice, three parties are involved: the home employer, the secondee, and the host organisation. The home employer retains the employment relationship. The host organisation directs daily work. Because both parties share responsibilities, a clearly drafted secondment contract is essential before the assignment begins. Without it, disputes over liability, costs, and obligations are common.
What is a secondee, and what does seconded mean?
A secondee is the employee who has been temporarily reassigned. When someone is described as “seconded,” they are currently working under a formal secondment arrangement. Secondment applies to employees sent abroad, placed with a partner organisation, or moved to a different internal division.
In most cases, seconded employees retain their salary, benefits, and accrued leave. However, the host organisation may offer additional allowances or top-up payments. Both parties should document these details in the secondment agreement. This avoids confusion and ensures the secondee understands their terms throughout the assignment.
How does seconding an employee work in practice?
Seconding an employee involves three stages: agreeing the terms, drafting a secondment agreement, and managing compliance throughout. The home employer continues to pay the employee. The host organisation typically reimburses those costs. Local labour law applies from the first day of the assignment.
For international secondments, complexity increases significantly. If the secondee moves to a new country, local employment law applies immediately. Tax treaties, social security obligations, and work permit requirements must be assessed in advance. Many HR managers therefore engage a detacheerder, a dedicated secondment provider, or an employer of record to manage this process. That approach reduces compliance risk and administrative burden considerably.
What should a secondment contract include?
A secondment contract must confirm the assignment duration, the obligations of each party, the reporting line, salary and benefit arrangements, and which employer handles compliance. Without these elements, disputes arise about liability, notice periods, and return obligations.
A well-drafted secondment contract should cover:
- Start and end date of the assignment
- Names of the home and host organisation
- Job role and responsibilities during the secondment
- Who pays the salary and covers work-related expenses
- Benefits, allowances, and entitlements that apply
- Terms for early termination or extension
- Applicable governing law and jurisdiction
A secondment agreement differs from a standard employment contract because it supplements rather than replaces the original relationship. Therefore, HR managers must ensure both documents align and do not contradict each other.
What is detachering, and how does it apply in the Netherlands?
Detachering is the Dutch term for secondment or temporary staffing. Detachering betekenis refers to the legal and operational meaning of this arrangement under Dutch employment law. A detacheerder is the organisation that employs and places workers with client companies. In the Netherlands, detachering is widely used in IT, engineering, finance, and professional services.
Under Dutch law, a detachering arrangement requires a written agreement. Therefore, the detacheerder carries full employer obligations, including payroll processing, tax reporting, and social security contributions. Meanwhile, the client directs daily work. In terms of risk, what is detachering without proper documentation? Misclassification between employment and independent contracting is closely monitored by Dutch authorities. Consequently, informal secondment structures that resemble employment expose companies to retroactive penalties and significant legal liability.
What are the benefits of seconding an employee?
Seconding an employee builds skills, strengthens partnerships, and enables cross-border operations without a permanent hire. As a result, it is a flexible way to manage talent across markets. In addition, companies gain from knowledge transfer, workforce agility, and faster international expansion.
Secondments also support employee development. Secondees gain international experience while remaining part of the home employer’s workforce. For HR managers, this reduces recruitment costs and retains institutional knowledge. Furthermore, a well-structured secondment agreement protects all parties and makes return transitions smoother at the end of the assignment.
How does an employer of record simplify international secondments?
An employer of record (EOR) acts as the legal employer for seconded workers in a new country. It handles payroll, taxes, and compliance, while the original company retains full operational control. This structure enables international secondments without establishing a local legal entity. EORs manage contracts, onboarding, and compliance with local labour laws, reducing risks for companies operating globally or entering new markets.
Key aspects of EOR secondment:
- Legal employer: The EOR assumes all legal responsibilities, including compliance with local tax regulations and employment laws.
- Secondment setup: When a company assigns a worker to a new country, the EOR employs them locally. The original company retains the worker for operational tasks.
- Simplified global hiring: Companies use EORs to hire in foreign countries without setting up local subsidiaries. This saves time and avoids high setup costs, which can exceed €70,000 per year for a fully operational Dutch entity.
- Risk management: EORs eliminate the risk of misclassifying workers or violating local labour laws.

Frequently asked questions about secondment
What is the secondment meaning in HR?
Secondment means the temporary assignment of an employee to another organisation, department, or country. The secondee keeps their original employment contract active.

The seconded meaning confirms that their home employment contract remains active throughout. Salary, benefits, and accrued rights are typically preserved. The assignment has a fixed end date, after which the employee returns to their home employer.
What is a secondment agreement?
A secondment agreement is the written document governing the arrangement between the home employer, host organisation, and secondee. Specifically, it covers the assignment duration, salary and expenses, reporting structure, governing law, and exit terms. Furthermore, a secondment agreement supplements the original employment contract and therefore clarifies responsibilities for all parties involved.
What is the difference between a secondment and a permanent transfer?
A secondment is temporary, the employee returns to the home employer at the end. A permanent transfer ends the original employment relationship and creates a new one with the receiving organisation. Secondments are lower-risk for both parties, making them useful for international assignments, pilot projects, and cross-organisational knowledge exchange.
What is detachering in Nederland?
Detachering is the Dutch term for secondment or temporary staffing. Detachering betekenis covers the formal employment and placement of workers at client organisations via a detacheerder. In the Netherlands, detachering requires a written agreement and full compliance with Dutch payroll, tax, and social security rules. Misclassification risks are significant without proper documentation.
How does an employer of record help with international secondments?
An employer of record becomes the legal employer in the destination country, managing payroll, taxes, social security, and local compliance. This allows companies to second employees internationally without establishing a local entity. The EOR handles the secondment contract and legal obligations while the original company maintains full operational control over the secondee.
