Industrial action in Amsterdam and Rotterdam is to cease after tug crews struck a five-year pay deal with their employer Svitzer Euromed.
Trade unions Nautilus and FNV Havens negotiated a five-year collective bargaining agreement (CBA) with the tug owner's management on Monday.
Tug crews wanted Svitzer to base wages on a 49-hour working week and reimburse them for unpaid hours, which each week account for 8.5 hours per person on average, according to Nautilus.
The long-running dispute has caused 11 strikes by Nautilus members this year, as TradeWinds has reported.
The deal will boost crew members' salaries by over 5% this year, which comprises a 3% wage increase plus consumer price index compensation.
Smaller additional wage increases will follow each year until 2023.
Asmae Hajjari, an FNV Havens official, said the unions had achieved "good results".
"This new collective labour agreement deal does justice for an important part to the extra hours they have started working since 2014," she said.
Svitzer stopped reimbursements for unpaid working hours in 2014 while the company underwent financial difficulties.
The parties also struck an agreement on saving extra-statutory leave days for early retirement and the safety of using temporary employees, Nautilus said.
