In a statement released today, the carrier states that, as circulation is expected to be affected, “the transport service will start from 9:30 am”.

Speaking to Lusa, during the previous strike, Anabela Carvalheira, from the Federation of Transport and Communications Unions (Fectrans), explained that the strike notice delivered by the unions for the 18th and 27th has to do with working conditions.

According to Anabela Carvalheira, the strike is based on the same reasons as the partial strikes held in March and on April 14, 22 and 29 and on May 4.
