A shortage of staff is now affecting a record 35% of cafes, bars, restaurants and hotels in the Netherlands, according to new figures from nationals statistics agency CBS.

The situation is even more acute in Amsterdam, where almost 40% of cafes and bars say they don’t have sufficient workers.

There are now around 23,000 vacancies in the hospitality sector, compared with just 6,700 in 2013 as the Netherlands emerged from the financial crisis. Some cafes and bars are even being forced to adjust their opening hours because of the lack of personnel, the Parool reported.

Nevertheless, cafe, bar and restaurant owners remain positive about their business prospects, with the confidence index at 1.9 in the fourth quarter of the year. This is, however, the lowest rating in six years, the CBS said.
