Hayes's first job was at the Southbury Training School in Connecticut.[9] She went on to teach government and history at John F. Kennedy High School in Waterbury. She also chaired the Kennedy SOAR Review Board, a "school within a school" that provided advanced instruction for gifted students, and was a co-adviser of HOPE, a student-service club at Kennedy.[8] In 2015, she was John F. Kennedy Teacher of the Year and then the Waterbury School District Educator of the Year.[8] In 2016 she was named National Teacher of the Year.[10]
This award won Hayes widespread media attention. "I really think that we need to change the narrative, change the dialogue about what teaching is as a profession," Hayes told The Washington Post. "We've spent a lot of time in the last few years talking about the things that are not working. We really need to shift our attention to all the things that are working." Appearing on Ellen DeGeneres's talk show, Hayes said she taught her students "kindness" and "community service."[11] After receiving the award, she addressed the annual meeting of the National Education Association. "I am so grateful to be a member of the NEA," she said, praising it for preventing the exploitation of the "altruistic character trait that all teachers possess".[12]
In 2018, Hayes ran for the Democratic nomination for Connecticut's 5th congressional district. Her difficult upbringing was a cornerstone of her campaign. “I know what it’s like to go to bed to gunshots outside,” she told an audience at a candidate forum. “I know what it’s like to wake up in the morning to a dead body in the hallway."[6]
Hayes won the primary on August 14, beating Simsbury First Selectman Mary Glassman, who was endorsed by the Connecticut Democratic Party, 62% to 38%.[13] In the November general election, she faced Republican Manny Santos, a former mayor of Meriden.[11]
Hayes supports public education and teachers' unions, and has credited her "union brothers and sisters" with playing a role in her success.[9] In the 2018 election, she was endorsed by the Connecticut Education Association.[14] Her candidacy was also supported by the Connecticut Working Families Party (CTWFP), with CTWFP state director Lindsay Farrell saying that her primary victory "demonstrates the value in electing and mobilizing teachers who will fight for public education, stand up to [Education Secretary] Betsy DeVos, and advocate the importance of collective bargaining."[11]
Hayes ran for reelection in 2022 and faced the most competitive election of her career.[21] She narrowly defeated Republican state SenatorGeorge Logan in the general election.[22]
Soon after winning a second term, Hayes circulated a letter to the Republican House leadership urging it not to place Representative Marjorie Taylor Greene on the House Education Committee, citing Greene's claims that the Sandy Hook Elementary School shooting and other mass school shootings were false flag operations. Sandy Hook is in Hayes's district.[26]
In 2023, Hayes voted against H.Con.Res. 21 which directed President Joe Biden to remove U.S. troops from Syria within 180 days.[29][30]
Transgender rights
During the United States House Committee on Education and the Workforce hearings regarding H.R. 734, a federal trans and intersex sports ban,[31] Hayes criticized the bill, stating "82% of trans youth have considered suicide and 40% have attempted suicide. This hearing, this legislation, this conversation further puts a target on the backs of students who are in the scariest times of their lives."[32]
Personal life
Hayes lives in Wolcott, north of Waterbury, with her husband and four children.[33]
