Tens of thousands of workers at restaurants and cafeterias like McDonald's and Starbucks across Germany have gone on strike.

The NGG unions have called for a warning strike in the so-called system gastronomy, which includes Burger King and Pizza Hut among others, as the second round of negotiations on the collective agreement ended without results, DPA reports.

Further negotiations in this branch with 120.000 employees should not take place until November - later than originally planned.

The NGG criticized the employers that in the second round "they did not move a millimeter according to the demands of the employees".

- That is why we are on strike, said the chief negotiator of the restaurant Mark Baumeister.

Prices in Germany have risen in the last few years, Baumeister recalled, adding that employees have a "huge need to get increased incomes.

"They expect real relief and significantly more money - instead, the employers did not even bring a new offer for the second round of negotiations." It is absolutely disrespectful to employees.

The NGG is demanding, among other things, a starting wage of 15 euros per hour for the lowest paid employees.
