"Robust contingency plans have been activated to protect operations and mitigate service disruptions, particularly during this demanding summer period, always with full respect for workers' rights," said a spokesperson for British airline Menzies Aviation, which owns 50.1% of the former Groundforce (the remaining 49.9% remained with TAP), in statements sent to the media.

The SIMA announced this week that it has filed two criminal complaints with the Public Prosecutor's Office against the management of SPdH/Menzies and TAP. One alleges violation of the Constitution and strike law, "based on the direct replacement of striking workers, unilateral changes to work schedules, suspension of breaks during periods of extreme heat, and various forms of repression and illegitimate pressure on workers," and the other alleges "payment of base wages below the national minimum wage (SMN), a serious and unacceptable violation of Portuguese labour law that violates the dignity of workers and constitutes an economic crime."

"Regarding the alleged legal proceedings, Menzies Aviation does not comment on legal matters," the company stated, assuring that it acts "strictly, in compliance with the law" and with its contractual obligations, "maintaining a firm commitment to fair labor practices and open and constructive dialogue with all stakeholders."

Menzies also emphasised that the priority "remains to ensure operational continuity and the quality of service provided" to customers and passengers.

When is the next strike?

SPdH/Menzies workers carried out the first of five strikes this summer last weekend, causing numerous delays and flight cancellations. The next four-day strike is scheduled for August 8th through 11th.

Strikes are also planned for August 15th through until 18th, August 22nd through until 25th, and August 29th through until September 1st.

The strike's underlying demands include an end to base wages below the national minimum wage, better wages, the enforcement of night shift pay, and the maintenance of parking access under the same terms and conditions "that have always been applied to them," according to the workers' representatives.
