[1] Nir also served as head of the Polish Waiter's Union, and in 1906 led what he claimed to be the world's first successful strike against tipping.

[4] Nir continued to play a prominent role in Poale Zion and was a member of the Jewish National Council and the Assembly of Representatives prior to independence.

In 1954, Ahdut HaAvoda (a faction related to the Left Poale Zion) broke away from Mapam, and Nir assumed membership of the new party.

He was returned to the Knesset on its list, when Tzipora Laskov resigned from her seat in October 1955, and again chaired the Constitution, Law and Justice Committee.

Nir retained his seat in the November 1959 elections, and chaired the committee for public services, but resumed his position as Deputy Speaker when the Knesset reconvened.
