Trade unions FNV, CNV and VNC want Minister Wopke Hoekstra of Finance to clarify his conditions for the billion-dollar support to KLM.

The unions have been acting against the demands of the government for some time. They are angry that employees are asked for a detailed pay sacrifice, while this is usually a matter that the employer must short-circuit with the staff at the collective labour agreement table.

According to the unions, it is currently unclear whether KLM or the Ministry of Finance took the initiative to include the wage sacrifices in the rescue package of The Hague. The airline and the government would designate each other as responsible.

The unions also want further details from Hoekstra about the consultations with KLM about the emergency loans, they write to him in a letter.

Trade unions at KLM had previously objected via Brussels to the package of requirements that The Hague deposited with the airline in exchange for 3.4 billion euros in aid.

The European Commission approved the aid, which comes in the form of direct loans and credit guarantees, on Monday.
