Carmen Sierra: Hartford Investigation Finds Anti-Harassment Policy Violations

The New England Voice obtained directly from Hartford City Hall the 23-page investigative report examined for this article. Reviewed by Isabel Calione, the report concludes that Carmen Sierra made comments about marital status, age and ethnicity that violated the city's anti-harassment policy.

The independent workplace investigation also found that Sierra's conduct discouraged employees from challenging the deletion of compensatory time or seeking approval to use accrued time because they feared retaliation.

The findings concern the treatment of employees inside an office responsible for collecting, depositing and reconciling city money, as well as administering pensions and investments. They raise questions about how Hartford responded to workplace concerns and what corrective action followed.

Dated July 27, 2026, the report was prepared by attorney Cindy M. Cieslak for Corporation Counsel Jonathan E. Harding and Human Resources and Labor Relations Director Marlene Fleeting. It contains accounts from the complainant, Chelsea Mott, ten numbered witnesses and Sierra herself.

Sierra denied several of the statements attributed to her. The investigator upheld some allegations and rejected others.

Mott raised her concerns on November 5, 2025. Hartford retained the investigator approximately November 25, according to the report.

Sierra announced her retirement on July 6, 2026. In her retirement letter, as reported by CT Insider, she cited her mother's recent death and her father's illness as reasons to devote her time to her family.

The investigative report is dated 21 days after that announcement. The chronology establishes that the investigation began months before Sierra's departure. It does not establish that its findings prompted her retirement or contradict her stated family reasons. The report's date also does not establish when it became public.

One of the central findings concerns a financial literacy symposium held on Saturday, May 31, 2025.

Mott, a Financial Systems Manager in the Custody of Funds unit, said she could not attend because she needed to take her son to a baseball game and had no one else available to do so.

According to Mott, Sierra called her into a private discussion, questioned how her absence would look and threatened to write her up and withhold raises and promotions if she did not attend.

Sierra denied making those threats. She told the investigator she had emphasized Mott's leadership responsibilities, offered to let her bring her son and explained that hours worked at the event could be used at another time.

The investigator credited Mott's account and concluded it was more likely than not that Sierra made threatening and intimidating statements related to Mott's marital status and ability to attend.

That conclusion drew on Mott's account, her reports to colleagues and a witness's recollection that she was visibly upset. Those colleagues were not presented as direct witnesses to the entire private conversation.

The investigator also concluded that Sierra made comments during a December 2024 budget meeting questioning Mott's salary in relation to her age.

The report credits Mott's account that Sierra said she should not make that much money at her age and made remarks demanding that she earn her salary. The investigator also considered other witnesses' accounts of similar comments and public criticism of employees.

Sierra denied making the statements. She said she had advocated for wage adjustments for women in the office and wanted Mott to develop her leadership skills.

On ethnicity, the investigator credited witness accounts that Sierra had said she needed to look out for Hispanic or Latino employees. The report also credits a witness's account that Sierra described Asian employees associated with an investment firm as not being the right type of minority.

The report makes an important distinction: the investigator found that ethnicity-related comments occurred, but did not conclude that Mott's treatment was discriminatory because of her ethnicity.

In its final conclusions, the report states that Sierra's comments about marital status, age and ethnicity violated Hartford's anti-harassment policy.

The investigation examined the handling of hours worked beyond employees' regular schedules.

The investigator found that the office's Chief Administrative Officer manually removed extra time above 80 hours in a two-week period when she was not informed of prior approval.

Mott's specific allegation concerning deleted compensatory time for October 19 through November 1, 2025, was classified as unfounded because the time ultimately was not deleted.

However, the investigator credited other employees' accounts that their time had been removed. She concluded that Sierra's conduct created a chilling effect: employees felt unable to challenge deletions or request and use accrued time for fear of retaliation.

The report also concluded that Sierra knew or should have known that Mott was working beyond her contractual hours without all of that time being accounted for in the timekeeping system.

The investigation did not uphold discrimination allegations involving permission to work from home or the ordering of ergonomic chairs.

It also exonerated Sierra regarding Mott's vacation approval. The investigator attributed the delay to staffing needs and the office's responsibility to maintain financial checks and balances while multiple employees were absent, rather than to Mott's age or ethnicity.

Those conclusions are part of the same investigation and are essential to an accurate account of its results.

The report establishes findings under city workplace policies. It is not a court judgment, and the material reviewed for this article does not establish that Mott has filed a lawsuit against Hartford or received a settlement or damages award.

It also does not identify the cost of the investigation. Without invoices, payment records or documents concerning any claim, there is no basis to state that taxpayers have paid a particular amount because of this case.

The next questions for Hartford are concrete: What did the investigation cost? What measures followed its findings? Were timekeeping procedures corrected? What protections were put in place for employees reporting concerns?

The report lists 29 exhibits submitted separately to Corporation Counsel. Those exhibits are not included in the 23-page document reviewed by The New England Voice.

Sierra's departure closed one chapter in the Treasurer's Office. The report leaves another open: how Hartford addressed findings that employees were intimidated and feared challenging the handling of their own work hours.
