Employers can become self-insurers under the Sickness Benefits Act (ZW) — financing sickness benefits for flex workers (sick agency workers, those with end-of-contract illnesses, no-risk policies) themselves instead of through the UWV. Advantage: direct control over reintegration and lower premiums. Disadvantage: financial risk in case of high absenteeism. The ZW self-insurance policy covers part of that risk. For employers with a high level of flex or large fluctuations in their workforce: a relevant consideration.

The short answer

  • What: bearing the risk yourself for Sickness Benefits Act payments to flex workers and those suffering from end-of-contract illnesses.
  • Alternative: UWV bears the risk (default).
  • Advantage: control over reintegration + lower costs with low absenteeism.
  • Disadvantage: financial risk in case of high absenteeism.
  • Insurance: Sickness Benefit deductible insurance covers part of the risk.

What is the Sickness Benefits Act?

ZW deductible insurance documentation

The Sickness Benefits Act (ZW) regulates sickness benefits for:

  • Employees whose employment ends during illness.
  • Temporary agency workers and flex workers with expired contracts.
  • Employee no-risk policy (UWV sickness benefit).
  • Unemployment benefit recipients who become ill.

Standard: UWV pays sickness benefit. Employer pays premiums via the UWV system.

What is self-insurance?

Employer chooses to pay sickness benefit themselves instead of through UWV. Responsibilities:

  • Benefit for flex worker (70% of wages, max 2 years).
  • Reintegration obligations (Gatekeeper also applies here).
  • Administration and reporting to the UWV.

Advantages:

  • Direct management of reintegration (no UWV intermediary).
  • Lower costs with stably low absenteeism.
  • Maintain employment during recovery.

Disadvantages:

  • High financial risk associated with long-term absenteeism.
  • Administrative burden increases.
  • UWV fines for non-compliance with the Gatekeeper.

The sickness benefit deductible insurance

Sickness benefit deductible premium 1-3% of flex payroll

Insurance covering the financial risk of self-insurance:

  • Reimburses wage costs during sickness benefit.
  • Covers reintegration costs.
  • Provides assistance with UWV procedures.

Premium: 1-3% of flex-wage bill — depending on industry and deductible.

Who is it suitable for?

  • Employers with high flexibility: temporary employment agencies, project-based sector.
  • Employers with a stable workforce: permanent employees with low absenteeism.
  • Employers with a low differentiated premium: appears to exceed the UWV premium.

Less relevant for SMEs with a small, stable workforce without flex.

Combining with WGA deductible

Similar concept: self-insurance is also possible for WGA (partial disability after 2 years of illness). Often, both are combined: fully bearing the costs of both ZW and WGA oneself; this provides maximum control but also maximum risk.

Honest recommendation

HR advisor discusses deductible choice

For employers without flex workers: ZW self-insurance is usually not relevant. For employers with substantial flex (agency, project, temporary): calculate the costs involved to determine if it is advantageous. Calculate UWV premium versus self-insurance + insurance + administration. If the outcome is favorable: self-insurance is virtually mandatory to absorb large fluctuations in claims.

For other topics: absenteeism insurance, WGA deductible and insurance for SME companies.

Frequently Asked Questions

What is ZW self-insurance?

The employer chooses to pay sickness benefits to flex workers and employees whose contracts are ending themselves, instead of through the UWV. The default is the UWV; self-insurance is optional, with different financial and operational implications.

Who is it suitable for?

Employers with substantial flexibility (temp agencies, project-based work), or a very stable workforce with low absenteeism. Less relevant for SMEs with a small permanent staff without flex workers.

How much does the insurance cost?

1-3% of the flex wage bill depending on the sector and deductible. Plus administration and reintegration costs not handled through the UWV. Compare with the UWV premium for a financial assessment.

What are the benefits?

Direct management of reintegration (no UWV intermediary), lower costs with stably low absenteeism, retention of employee employment during recovery, and a better information position regarding absenteeism trends.

Disadvantages?

High financial risk associated with long-term absenteeism, increased administrative burden, and UWV fines for non-compliance with the Gatekeeper Act. For unstable employers or poor risk management: financially unattractive.

Combine with WGA deductible?

Yes, employers often do both simultaneously. ZW for the first 2 years, WGA for thereafter. Maximum control and a consistent reintegration policy throughout the entire process. Maximum financial risk — insurance is essential.

How to switch?

Registration with UWV before January 1st for effective the following year. Requirement: sufficient solvency to cover the risk. Take out parallel insurance. For a smooth transition: engage an HR advisor or insurance advisor with sickness benefit expertise.
