Collective Labor Agreement for a year and a half with a 6 percent salary increase final agreement

On 21 July 2022, with 100 percent approval from their respective boards and members, the Employers' Association for Research Institutes (WVOI) and the employees' organisations FNV, CNV Onderwijs and AOb converted their previous negotiators' agreement for a new Collective Labour Agreement Research Institutions into a final collective labour agreement.
The agreement runs from 1 January 2022 to 30 June 2023 inclusive. The most important arrangements made concern salaries and the extension of paid parental leave.


Salaries will increase by 4 percent with effect from 1 August 2022. In addition, every employee employed on 1 August 2022 will receive a one-off payment of 1,050 euros before tax, with this payment being calculated according to the size of the contract and the number of months for which the employee was employed in the period from 1 January to 31 July 2022.
Salaries will increase by 2 percent on 1 January 2023.

Extension of paid parental leave

As of 1 August 2022, all working parents are entitled to nine weeks of paid parental leave under the new Paid Parental Leave Act (Wbo). This Act states that every working parent may take nine weeks of paid parental leave during the child's first year of life, at 70 percent of the daily salary paid by the Employee Insurance Agency (UWV). The Collective Labour Agreement Research Institutions already included a scheme for paid parental leave. This scheme will be adjusted based on the new Act. As of 1 August, employees may take thirteen weeks of paid parental leave at 55 percent of their salary, provided the leave is taken before the child's fourth birthday. This rate will be increased to 70 percent if these weeks are taken in the first year of the child's life. After the child's first birthday, remaining hours from the thirteen paid weeks may still be taken at 55 percent of the salary, provided the hours are taken before the fourth birthday.

ABP pension

All NWO-I employees, except those that are funded by a European grant, are insured with the National Civil Pension Fund ABP for both old-age pension, survivor's pension, and disability. You can find elaborate but clear information on the ABP website. Unfortunately, this information is only available in Dutch. On the ABP website, you will find information about your pension. Unfortunately, this information is not available in English. Via you can arrange your pension matters online. For example, you can plan your pension or change your preferences. To help participants use the website, ABP has made a webpage available with short instructional videos. These simple videos focus on the following subjects: retirement, survivor's pension, partner's pension, and digital post. The videos are only available in Dutch and can be found on the website of ABP. In the annex, you will also find a leaflet about building up your pension via the ABP.
Your personnel officer or employees from the P&O Department of NWO-I will be happy to inform you or answer your questions (also in English). You may not reproduce the employment conditions without prior written permission of NWO-I.
