Metro Manila (CNN Philippines) — Fewer Filipinos are satisfied with the performance of Vice President Leni Robredo just as her resignation from the Cabinet made headlines, according to a nationwide poll.

The Social Weather Stations (SWS) said Robredo's net public satisfaction rating dropped 12 percentage points from +49 in September to +37 in the latest December 3-6 survey.

Despite the steep slump, SWS still considers Robredo's rating as "good."

SWS classifies net satisfaction ratings over 70 percent as "excellent," +50 to +69 "very good," +30 to +49 "good," and +10 to +29 "moderate."

Of 1,500 respondents, almost 6 in 10 or 58 percent said they were satisfied with Robredo's performance against 21 percent who said otherwise, yielding a net satisfaction rating of +37.

Robredo announced her resignation from her Cabinet post as chairperson of the Housing and Urban Development Coordinating Council (HUDCC) on December 4.

She said President Rodrigo Duterte's order for her to "desist from attending all Cabinet meetings" was "the last straw" in a series of efforts to supposedly derail her from doing her job.

Although the hashtag #LabanLeni landed on top of Twitter's trending as netizens poured out their support for Robredo, the SWS survey showed a wavering of public approval for the vice president.

Results of the survey, which has a margin of error of ±3 percent, were released by SWS's media partner BusinessWorld on its website Wednesday.

Top gov't officials' ratings drop

Public satisfaction with the highest government officials also dropped, the survey showed.

House Speaker Pantaleon Alvarez's rating slipped 13 points from +22 in September to only +10 in December (rounded-off).

Chief Justice Maria Lourdes A. Sereno's rating also fell 10 points from +26 to +16.

Public satisfaction of Alvarez and Sereno still stayed within the "moderate" category, SWS said.

Meanwhile, Senate President Aquilino Pimentel's rating was "good" at +30, but was also down 7 points from his previous +37 rating.

The President's "very good" public satisfaction rating of +63 was also a percentage point down from the +64 he gained from the September survey, according to results of the same survey which were earlier released by SWS.
