During the 1990s and 2000s, she worked as a political and current affairs journalist for radio stations in Chile, where she achieved high recognition for her activity.

There she began to make her editorials, which were not without controversy, due to the leading role she took on the station, different from the traditional space that women have been given in Chilean communications.

[13][14] She began her television career after turning 40, in the newscast Hora 25 from La Red, along with Verónica Franco, which was the first program to have a female duo in the conduction.

Her time on television ended abruptly; In mid-2015, the Hora 20 program was taken off the air due to the closure of La Red's press department.

[18] However, after a meeting with the Democratic Revolution party and the Autonomist Movement, she decided to consider an eventual pre-candidacy, freezing her work at Radio La Clave and postponing other projects she was planning: to carry out a diploma and a goldsmith course.

In an interview with Paula magazine in November 2014, she stated that her reasons for such are that “we still earn up to 40% less than men for the same job; Despite being 50% of the population in the country, we are less than 20% in political positions, in company directories, in national awards and general management; and it's not because all women want to be mothers".

[26] On 10 June 2020, Sánchez accused Secretary of State Jaime Mañalich of having an "erratic" strategy to handle the coronavirus pandemic in Chile.
