Later in the same month, after a strike was worker's rally broken up in Bucharest and the newly created Socialist Party of Romania (PS) repressed, Flueraș and Jumanca, urged by Constantin Titel Petrescu, met with King Ferdinand I and Premier Ion I. C. Brătianu, persuading them to grant concessions to the labor movement.
In late 1919, Flueraș, Jumanca, and Ilie Moscovici carried unsuccessful negotiations for a merger between Alexandru Averescu's People's League and the Socialist groups; talks were mediated by Constantin Argetoianu.
[7] Alongside Gheorghe Cristescu, Alexandru Dobrogeanu-Gherea and others, Flueraș was a delegate to the Second Congress of the Comintern in Moscow, where the matter of the PSR's joining of the international body and its support of Bolshevik lines were debated.
[9] When the authoritarian regime of King Carol II was imposed in 1938, he supported the change and remained active in the guilds established by the new corporatist structure of the National Renaissance Front (as a member of the Upper Economic Council and the Senate).
[12] Flueraș remained opposed to the main Social Democratic Party (PSD), and accused the growing Soviet influence which had found its advocates inside the latter political group (the wing led by Lothar Rădăceanu and Ștefan Voitec).
He also allegedly refused office in the Communist-backed Petru Groza government, and rallied with Constantin Titel Petrescu's Independent Social Democrats, which had split with the PSD over the issue of running common lists with the communists.
