On 18 March, eight security guards used physical force to remove Ayhan Uygun, education secretary of the aviation union Hava-Is, affiliated to the International Transport Federation (ITF), from a building at Sabiha Gökçen International Airport, Istanbul. Mr. Uygun was attempting to hold a meeting with workers at the engine maintenance company Turkish Engine Centre (TEC) to update members on collective bargaining talks taking place with TEC. It is understood that a disturbance followed, during which a number of union members intervened, and that a protest was held by workers over the guards’ actions. Four TEC workers were subsequently dismissed, apparently over their alleged roles in the incident.
