Signed by the PAN Party, the proposal was approved with votes against from the PCP (Portuguese Communist Party) and Chega (Chega), abstentions from the PSD (Social Democratic Party), PPM (People's Monarchist Party), CDS-PP (CDS – People's Party), and non-registered member Margarida Penedo (who left the CDS-PP), and votes in favour from BE (Bloco de Esquerda), Livre, PEV (Ecologist Party "The Greens"), PS (Socialist Party), IL (Iniciativa Liberal), MPT (The Earth Party Movement – Earth Party), and two independent members of Cidadãos Por Lisboa.

Recalling the recent heatwave between late June and early July, which saw temperatures exceed 40 degrees Celsius in Lisbon, PAN's sole member of parliament, António Valente, considered it "unacceptable and inhumane" to have people working outdoors "exposed to extreme temperatures," particularly those involved in urban cleaning, green space maintenance, and waste collection.

"As heatwaves occur more frequently and are not always predictable at the territorial level, scientists recommend that action plans be developed to reduce the risk of deaths and other injuries associated with extreme weather," the PAN member of parliament noted.

António Valente also noted that, for example, Spain already has national legislation regarding protective measures for workers exposed to extreme temperatures, and municipalities such as Seville, Malaga, and Córdoba have begun to reorganise urban cleaning workers' shifts to times when sunlight is lower, such as early morning hours.

PCP MP Fábio Sousa lamented the absence of any reference to initiating negotiations with labour unions.

Chega's Patrícia Branco considered that "climate activism is never-ending," saying that the PAN's proposal represents "a new rigmarole about climate change."
