On its website, the Lisbon-based transport company states that "some disruptions to the regular passenger transport service" may occur following the meeting.

"Carris will make every effort to minimise the inconvenience of any partial service disruptions and thanks customers for their understanding," it reads.

At the plenary meeting, which will take place in Santo Amaro, Oeiras, where the company is headquartered, the union will decide whether to accept the company's final proposal or whether the workers will continue their struggle.

"Either this final proposal [...] can be consolidated into the AE [Company Agreement] text and from there reinforce in the next negotiation processes the demand for further reductions to achieve the central objective, which is a 35-hour workweek for all workers, or the workers understand otherwise, and then the struggle will inevitably have to continue, with the day of struggle already approved at the last plenary meeting," the statement reads.

According to STRUP, the proposal submitted for discussion and vote in the plenary session maintains the proposal previously presented and discussed in the last plenary session regarding travel payments for transit workers and reaffirms that management will not consider the strike for the purposes of penalizing the vacation schedule.

On the other hand, it adds, the proposal evolves regarding the timetable for reducing the workweek to 39 hours: "It accepts that the reduction in the PNTS (normal workweek period), for all workers, be implemented not in December 2026, as we proposed, but in January 2027. This reduction will have an impact on the increase in the hourly rate." The existing shorter schedules remain in effect.

On July 17, the Federation of Transport and Communications Unions (Fectrans) announced that Carris workers would go on strike on September 18 and refuse all overtime work in the second and third weeks of that month, as they could not reach an agreement with the company.

In April, Carris reached an agreement with workers for a salary increase for 2025.

However, union leader Manuel Leal noted at the time that the implementation of the 35-hour work week and the payment method for trips were still under discussion.

Carris provides urban surface public passenger transportation services in the municipality of Lisbon, primarily by road, and is administered by the Lisbon City Council.
