More than 60 flights were delayed at Schiphol airport, Amsterdam in the Netherlands on Monday due to a strike by KLM ground service staff. More strikes are scheduled later this week.
The two-hour strike at the Schiphol airport, Amsterdam, from 6 am to 8 pm GMT, was aimed at influencing ongoing negotiations between trade unions and KLM, the Dutch arm of Air France-KLM, on wages and working conditions.
But the Federation of Trade Unions (FNV) said the company had not responded and a second strike was scheduled for the same time on Wednesday.
Trade unions are demanding an 8 percent increase in wages over two years, as well as more full-time employees and better working hours.
KLM on Thursday offered a 6-7 percent wage increase over three years, which was rejected by trade unions.
