In a note posted on the Presidency of the Republic's website, Marcelo Rebelo de Sousa welcomed this "tripartite understanding", saying that it was signed "by the Government, by the union confederation UGT and by the business confederations CAP, CCP, CIP and CTP".

"This tripartite understanding is an important contribution to promoting a climate of trust and social peace, which is necessary to overcome the current public health crisis and to jointly and successfully face the present and future economic and social challenges", considered the head of State.

The signing of this commitment, not signed by the CGTP-IN union central, took place on 12 May at a ceremony at the National Palace of Ajuda, in Lisbon, with the presence of the Prime Minister, António Costa, and the Minister of State and Economy, Pedro Siza Vieira.
