Kenya’s aviation sector faces possible disruption after the Kenya Aviation Workers Union (KAWU) issued a seven-day strike notice, demanding the resignation of the Kenya Airports Authority (KAA) board over what it terms incompetence and mishandling of key decisions, including the controversial airport leasing deal that was later cancelled.

KAWU Secretary General Moses Ndiema said the strike could begin any time after the notice period lapses but did not specify the exact date.

“The epitome of the board’s incompetence and lack of touch with reality is the recent events involving the Adani deal and other decisions,” Ndiema said in a letter dated September 23.

If the strike goes ahead, operations at Jomo Kenyatta International Airport (JKIA), one of Africa’s busiest hubs could be severely affected.

Last year, JKIA workers staged a day-long strike to protest plans to lease the airport to India’s Adani Group, a move that was eventually scrapped after the company and its executives were indicted in the U.S. over bribery allegations, which Adani has denied.

The KAA board has yet to respond to the union’s demands.
