The union representing pilots for German airline Lufthansa says that they will strike if the airline does not improve its offer on wages and working conditions. The union is asking for raises and better working conditions, with the airline offering less than asked for. Ground-staff staged a one-day walkout this week, grounding the vast majority of the airline's flights. That union has said that they will strike again if talks early next week are not successful.
