There is a revolt brewing in the City Council.

Ninety-one current staffers and 32 former employees of the City Council sent a letter to Speaker Corey Johnson on Friday, four days after the council voted to punish — but not expel — Councilman Andy King for harassing employees, retaliating against them and abusing the powers of his office. King is currently serving a 30-day suspension without pay and will be subject to a $15,000 fine.

Staffers who spoke with NY1 under condition of anonymity for fear of reprisal said the King episode was "the last straw." They say for years, some Council members have regularly "mistreated, intimidated, and underpaid staff."

"We're not going to tolerate this behavior anymore. We wanted to send a clear message that we do not agree with the vote the Council took," one staffer said.

There are 900 people employed by the Council, including the central staff, a team of lawyers, policy analysts, budget experts and strategists who report to the speaker. There are also hundreds of workers spread out across 51 Council districts. They report to individual members.

"If you're a resident of our district, we are going to work our hardest to serve you. That includes long hours, overtime that we don't get paid, weekends that we don't get compensated for, and we all do it for the love of government and the work that we're doing," one staffer said.

The group is currently considering worker action, a strategy some of them say they're willing to take if it means the Council will act.

"The main thing in our minds is the safety and the security of our fellow colleagues. These jobs are very stressful, they're hard some of them are very underpaid and we pour our hearts into these roles because we believe in public service," one staffer said.

The Council recently updated its sexual harassment and workplace behavior rules and retained Redwood Enterprise to audit its policies. The same firm was hired by Sen. Bernie Sanders' presidential campaign to address issues of discrimination and sexual misconduct. Johnson also increased the budget allowing for some salary increases.

"I hear them. This is an important conversation to have," Johnson told NY1 on Friday.

He says the Council is in the midst of a culture shift.

"I think that we have an endemic, systemic sexism, racism, misogyny, homophobia that exists in society, even in a progressive city like New York City and even in the City Council," Johnson said.
