Prior to joining the SSP on its formation in 2019, she was at different times a member of the League of Social Democrats of Vojvodina (LSV) and the New Party (Nova).

[13] The Democratic Party (DS) and its allies won the election and formed a coalition government that included the LSV, and Tepić was appointed as secretary for sports and youth in Bojan Pajtić's administration.

[14] This notwithstanding, some educational material provoked a backlash from socially conservative groups; the Democratic Party of Serbia (DSS), which held four seats in the assembly, argued that one publication "promoted homosexuality" and that Tepić should resign as secretary.

[15][16] The Serbian Progressive Party (SNS) and its allies won majority victories at both the republican and provincial levels; a new SNS-led government was formed in Vojvodina, and Tepić stood down from her cabinet role on 20 June 2016.

[19] The Progressive Party and its allies won the election, and Tepić served in opposition; this notwithstanding, she was appointed as head of the assembly's committee on European integration.

[20] Tepić resigned from the LSV in January 2017, in protest against party leader Nenad Čanak's decision to contest the 2017 Serbian presidential election rather than supporting the candidacy of Saša Janković.

The following month, Živković and Tepić joined with three former members of the Enough Is Enough (DJB) association to start a parliamentary group called the Independent MPs Club.

[26] In the same period, Tepić reported receiving death threats from right-wing groups, and Živković urged the government to assess whether she required protection.

[27][28] Meho Omerović, the chair of the assembly's committee on human and minority rights, condemned the threats against her and urged the police to ensure her safety.

[33] Like several other opposition parties, the SSP began a policy of non-participation with state institutions, including the national assembly, in 2019 and ultimately boycotted the 2020 parliamentary election.

She has accused the regime of involvement with organised crime groups, charging that the government created the notorious Belivuk clan before turning against it.

[34] In April 2021, she accused Dragan Marković, the leader of the United Serbia (JS) party and an ally of the SNS-led administration, of organising the prostitution of women and girls, some underage, at a prominent nightclub in his home community of Jagodina.

Tepić appeared in the sixth position on the coalition's list and was elected to a fourth assembly term when it won sixty-five seats.

"[45] She ended the strike after twelve days on 30 December 2023, saying that it had achieved its goal of bringing international attention to what she described as the "shameless election theft in Serbia."
