BERLIN – German trade union Ver.di has called on Ryanair Holdings PLC cabin crew based in the country to go on a one-day strike as it said that a round of negotiations with the low-budget airline’s management last week was unsuccessful.

The union said that the negotiations affect about 1,000 staff and that Ryanair hasn’t met its key demand for a “substantial increase in pay,” as well as the introduction of a basic salary for all flight attendants.

A spokesperson for the union said the salaries of flight attendants at Ryanair are so low that they are “insufficient to ensure a decent standard of living.”

The strike is scheduled for Wednesday.

Ryanair has proposed wage increases which were “completely out of the question,” the union said.

London-listed shares at 8.58 am GMT were down 1.2 percent at 1,162.23 pence.
