The minimum services are being ensured, everything is within normality, Costa said at the end of a briefing with the Civil Protection agency.

The National Union of Dangerous Goods Drivers (SNMMP) said earlier that drivers would fail to comply with minimum services because it said that the government and companies are not complying with the right to strike.

Monday is the first day for the drivers on a strike scheduled for an indefinite period aiming to demand compliance with the agreement signed in May, which provides for a salary increase, from the road hauliers’ association, ANTRAM.

The strike was called by SNMMP and by the Independent Freight Drivers’ Union (SIMM), and the Union of Road and Urban Transport Workers of the North (STRUN) was also associated to the strike.

The government decreed minimum services between 50% and 100% and declared an energy crisis, which implies "exceptional measures" to minimise the effects of the stoppage and ensure the supply of essential services such as security forces and medical emergency.
