The “conventions” are the benefits or “perks” enjoyed by public servants who work in state-owned banks, municipalities, universities and autonomous institutions.

The possibility of the imposition of a blanket ban on the perks has been mooted in recent weeks in the country, La República reports in Spanish.

In the latest resolutions, a pattern is being established that there is a greater awareness of the impact that collective agreements have on public budgets and services, said Otto Guevara, ex-member of the Partido Movimiento Libertario, while Albino Vargas, trade union leader of ANEP, denounces a systematic attack.
