A prolific writer, he spearheaded the second successful modernist movement in Filipino poetry together with Mangahas and Antonio. His earliest pieces of literary criticism were collected in Ang Makata sa Panahon ng Makina, now considered the first book of literary criticism in Filipino. Later, in the years of martial law, he set aside modernism and formalism and took interest in nationalism, politics and activist movement. As a critic, his critical works deal with the issue of national language. Aside from being a critic, Almario engaged in translating and editing. He has translated the best contemporary poets of the world. He has also translated for theater production the plays of Nick Joaquin, Bertolt Brecht, Euripides and Maxim Gorki. Other important translations include the famous works of the Philippines' national hero, José Rizal, namely Noli Me Tangere and El filibusterismo. For these two, he was awarded the 1999 award for translation by the Manila Critics Circle. Almario has been a recipient of numerous awards such as several Palanca Awards, two grand prizes from the Cultural Center of the Philippines, the Makata ng Taon of the Komisyon sa Wikang Filipino, the TOYM for literature, and the Southeast Asia Write Award of Bangkok. He was an instructor at the Lagao Central Elementary School from 1969–1972. In 2003, he was appointed Dean of the College of Arts and Letters at the University of the Philippines DIliman. On June 25 of the same year, he was proclaimed National Artist for Literature. Almario is also the founder and workshop director of the Linangan sa Imahen, Retorika, at Anyo, an organization of poets who write in Filipino. Award-winning writers and poets such as Roberto and Rebecca Añonuevo, Romulo Baquiran Jr., Michael Coroza, Jerry Gracio, and Vim Nadera are but some of the products of the LIRA workshop. He was a founding member of the Gallan sa Arte at Tula, along with fellow poets Teo Antonio nd Mike Bigornia.
