FRANKFURT, Aug 14 (Reuters) - Two specialised unions at

Deutsche Lufthansa's leisure airline Discover on

Wednesday said they were preparing strikes after talks over

working conditions at the unit have not yielded results,

challenging an accord struck by another union.

Strike ballots will start on Thursday and last until

Wednesday next week, pilots' union VC and cabin crew union UFO

said in a statement.

VC President Andreas Pinheiro said the aim was to achieve

collective agreements with better conditions for workers.

He added the airline could avoid strikes by resuming and

concluding negotiations with VC and UFO.

VC and UFO are rivals of the much bigger services union

Verdi. Last week, Verdi struck a collective bargaining agreement

with Discover for the first time since the Lufthansa brand began

operating in 2021, following several strikes.

The agreement at the time covered 500 cockpit workers and

1,400 members of the cabin crew.

A Discover spokesperson on Wednesday pointed to the deal

struck with Verdi. "Our focus is now on ensuring that the

collective agreement is implemented and can take effect", she

said.

Discover hailed the deal last week, arguing it would give

passengers confidence in their travel plans after strikes at

various airlines have hit the industry in recent years.
