Employees of towing company Svitzer in IJmuiden have deposited the work since 12 noon on Saturday afternoon. It is not the first time they strike. The group’s tugboats are chained, so that much incoming and outgoing shipping traffic on the North Sea Canal is not accompanied. The 63 employees demand that they be paid for all hours worked. In 2014, the company was in a financial crisis. To save the company, the staff was willing to work an extra 8.5 hours per week on average without being paid for these hours, FNV Havens reports. “In the meantime, however, the company is writing black numbers again. That is why the employees demand that the extra hours worked be paid from now on, “said a spokeswoman for the FNV. Svitzer has made a five-year collective labor agreement, in which wages increase by 1% each year. But the employees reject this. The FNV spokeswoman says that if Svitzer does not cross the bridge with the payment of the extra hours, the actions will only become more intensive.
