AMSTERDAM, Jan 19 (Reuters) - Thousands of metal and electrotechnical workers in the Netherlands are planning to go on strike from Thursday in demand of better pay, labor unions said on Tuesday.

Workers at the factories of chip sector supplier ASML , truck builder DAF and steel maker ThyssenKrupp will kick off the strikes on Thursday, followed by colleagues at Siemens and Scania among others, the unions said.

Unions demand a higher pay rise than the 2.25% over two years that employers have offered so far and also want more options for workers to decide on their schedules.

A labour agreement for the metal and electronics sector would cover around 160,000 people in the Netherlands. (Reporting by Bart Meijer, editing by Louise Heavens)
