According to data from Lusa, the number of cancellations, between arrivals and departures, ranged from 18 on Friday to six on Sunday, with a source from the Metallurgical and Related Industries Union (SIMA) estimating slightly higher numbers.

The same source pointed to "significant delays" in operations and criticized the company for not allowing "a fair strike."

On its website, ANA published a notice alerting passengers that, due to the company's strike, which "involves several airlines, such as TAP, airport operations may be disrupted during the following periods: July 25-28; August 8-11; August 15-18; August 22-25; and August 29-September 1," urging them to contact their "airline or travel agent before going to the airport."

Menzies workers began the second four-day strike on Friday, out of a total of five planned for the summer season, with the company and union exchanging accusations of unwillingness to engage in dialogue.

The strikes were called by the Metallurgical and Related Industries Union (SIMA) and the Transport Union (ST) to end basic wages below the national minimum wage, improve wages, and enforce night shift pay, among other demands. This second strike began at midnight on Friday and ended at midnight today.

A new strike is scheduled, along similar lines, next weekend.

Menzies Aviation, for its part, reported on August 1st that it had activated contingency plans to mitigate disruptions to ground handling services at airports and assured that it operates in compliance with the law and with "full respect for workers' rights."

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