In this study, we examine how the security of tenure (proxied by both inter- and intra-party electoral advantage) affects the engagement and political performance of members of parliament (MPs). Using data from the lower chamber of parliament in Poland for the period 2005–2019, we provide evidence that intra-party electoral advantage correlates with MPs’ efforts and political performance. A more secured position of an MP vis-à-vis their co-partisans leads to a decrease in the number of parliamentary speeches, statements, interpellations, and lower voting turnout. Therefore, it appears that MPs whose political survival is less uncertain work less hard than MPs with a more precarious future.
