The brother of Jan Antonín Bata, Hynek Bata was born in the Haná town of Kroměříž. He graduated from the municipal and bourgeois school in Zlín and in 1912, at the age of 14, he entered the service of his half-brother Tomáš in the family business Tomáš and Antonín Bat'a. Under Tomáš's supervision, he gained his first professional experience, first as an apprentice in the underwear workshop. In the summer of 1914, shortly after the outbreak of the First World War, he was put in charge of production allocation and administration of costing at the age of sixteen. Before going to the front (1916-1918), he was at the head of the newly introduced production segment, tannery, to which he remained loyal to the company after his return from military service in November 1918. As a master tanner, he gained experience in the American tanneries in Newark, but also in Ford's factories (1924). He put his acquired knowledge to good use first in the management of the tanneries in Zlín and the concern's plant in Třebíč-Borovina (1931). Subsequently, he was entrusted with the transfer of the Zlín tanneries to Otrokovice and the building of the local auxiliary factories.

In 1939, he was appointed a member of the Bata Concern's management group and, together with other top employees (Marie T. Bata, D. Čipera, J. Hlavnička, F. Malota and H. Vavrečka), he was awarded a seven per cent share in the shares of Bata, a. s., Zlín at the general meeting on 27 November 1939. Hynek Bata's name appeared alongside Václav Royt in the official announcement of the establishment of the Bata concern in Zlín, addressed to the District Office in Ledč nad Sázavou at the beginning of June 1939. In it, the "protocol" Bata company announced the establishment of a branch plant of the main factory in Otrokovice-Batau, for the production, storage and sale of all kinds of footwear "according to the factory with a location in Zruč nad Sázavou". Hynek Bat'a and Václav Rojt were appointed responsible deputies of the branch plant of Bat'a, a. s., Zruč nad Sázavou (Bat'a, a. s., Production Plant in Zruč nad Sázavou).

Hynek Bata left the national company Bata after his dismissal on 27 March 1946. In 1948 he left Zlín and emigrated to become a close associate of Tomáš Jan Bata and a builder of tanneries of the French concern in Hellocourt and on three other continents. He retired in 1965.
