A security staff walkout is expected to disrupt flights at Frankfurt Airport

After airport security employees called a 24-hour “warning strike” in protest of stalled wage and conditions discussions, Frankfurt International Airport (FRA) warned of “severe disruptions and aircraft cancellations” on Tuesday.

Frankfurt Airport stated in a statement that it will be compelled to close all of its passenger security screening sites on Tuesday for travelers beginning their journey in Frankfurt. The airport intends to maintain the transfer passenger screening lanes open, but has cautioned that delays and disruptions are possible.

On Tuesday, security guards are likely to strike at Hamburg (HAM), Stuttgart (STR), and Karlsruhe/Baden-Baden Airport (FKB), in addition to Frankfurt. On Monday, warning strikes began at six German airports, including Berlin (BER), Cologne (CGN), and Dusseldorf (DUS) (DUS).

As a result of the strike, Lufthansa warned of “significant restrictions” in its flight schedule, and recommended travelers planning to fly on Monday or Tuesday to bring as little hand luggage as possible.

After three rounds of negotiations with the Federal Association of Aviation Security Companies that failed to break the deadlock over-improved pay for around 25,000 airport security workers, the Ver.di union staged the walkouts.

A typical salary disparity between East and West Germany, according to Wolfgang Pieper, a union negotiator, is a sticking issue.

The union is proposing a minimum wage increase of 1 Euro per hour. Workers at Munich Airport (MUN) have also been asked to join the strike.

Ver.di asserts To fulfill the post-pandemic demand, the German aviation sector is struggling to find enough staff. Similar challenges with recruitment are plaguing the aviation industry in Europe and North America.
