Workers at Vestas in Germany on Monday started a five-day strike in an attempt to push through salary increases and force the wind turbine OEM to grant collectively agreed working conditions for its staff.

Most of the company’s about 1,700 employees in the country work in the service business.

“We want to put pressure on the issues that are important to employees," said Martin Bitter, managing director of the powerful metal workers union IG Metall in Rendsburg, northern Germany.
