He was hired by the Polish National Theatre in 1782 and became its director a year later (1782–84), proving to be an enterprising impresario by organizing tours to cities like Grodno and Dubno.

His second term as director of this institution, lasting from 1790 to the fall of the Kościuszko Uprising in 1794, consisted of building a real national stage with an artistic, social and civic mission.

Bogusławski was due to be arrested for staging “The Presumed Miracle/Krakovians and Highlanders,” but apparently escaped through the intervention of the Royal Marshall Moszynski.

Bogusławski introduced Classical tragedies to the Polish stage and did the same for Shakespeare, mounting productions based on translations and adaptations of the Bard's works.

Bogusławski was a proponent of classical French principles initially, but later shifted his focus to moralizing German dramas that he saw as being closer to life.

He directed the plays of Jean Racine, Molière, Voltaire, Pierre Beaumarchais, Denis Diderot, Friedrich Schiller and Gotthold Ephraim Lessing.

Bogusławski helped many actors to develop their talents, his protégés including Kazimierz Owsinski, Alojzy Żółkowski, Agnieszka and Tomasz Truskolaski, Franciszka Pierożyńska, Bonawentura Kudlicz, Józefa Ledóchowska, Ludwik Dmuszewski and many others.

He cooperated frequently with painters Antoni Smuglewicz, Jan Bogumił Plersch, Innocento Maraino and Antonio Scottio, and with exceptional musicians like Józef Elsner and Karol Kurpiński.

In 1811 he organized Poland's first School of Drama, simultaneously writing a textbook titled Dramaturgia, czyli nauka sztuki scenicznej dla Szkoły Teatralnej napisana przez Wojciecha Bogusławskiego w Warszawie 1812 (Dramaturgy, or an Instructional Stage Art Program for a Theatre School Written by Wojciech Bogusławski in Warsaw in 1812).

Toward the end of his life he wrote and published his Dzieje Teatru Narodowego (Annals of The National Theatre), and also compiled and printed his Dzieła Dramatyczne (Dramatic Works).
