Salary and employment agreement

Salary planning

NWO-I pays your salary on about the 24th of each month. In principle, the P&O Department NWO-I will process changes that have come in no later than the first of the month within the same month. Therefore please notify us about any changes in address, changes in IBAN (bank account), study cost claims etcetera, as soon as possible.

Salary table

You can find the table on the website of WVOI, see the link in the second sentence below the image on this webpage: CAO-OI (NL) – Werkgeversvereniging onderzoekinstellingen (Dutch only).

Employment contract and salary

At the start of your employment, NWO-I enters into a written employment contract with you. You will receive two copies of this employment contract and you will be asked to sign and return one of these copies. Usually, you will also be asked to supply other documents, such as a copy of your proof of identity, a copy of the relevant diploma et cetera.

Whether or not you receive an annual salary increase depends on the grade of the salary scale when you started employment. As long as the highest grade on the salary scale has not yet been achieved, then in the event of good performance, an annual salary increase will be applied. This increase will take place on the first of the month in which you entered employment.

Your line manager will hold a formal interview with you each year (see interview cycles on this website). Your line manager will submit a copy of the report of this interview to your P&O Department.

Collective Labour Agreement 2025-2026: increase of salary

The amounts in the salary scales have been structurally increased by 1.9% as of 1 October 2025. As of 1 January 2026, the amounts in the salary scales have been structurally increased by 3%. This means that a wage increase of 4.9% has been agreed for the duration of the collective labour agreement. 

Every employee who is in service on 1 November 2025 will receive a one-off payment of €900.00 gross. This payment will be proportional to the extent of the employment contract and to the number of months that the employee has been in service from 1 January 2025 to 31 October 2025. 

In accordance with the usual system, this increase will be reflected in pensions and benefits.
