Pauley Perrette left NCIS in May 2018 after fifteen seasons. Her exit became a case study in workplace communications, executive responsiveness, and the limits of vague corporate statements. Eight years on, what happened, what CBS said, what changed on set, and what every studio communications team should take from it.
Updated June 29, 2026.
The Fact Block
The actress: Pauley Perrette played forensic specialist Abby Sciuto on NCIS from the show's 2003 premiere through Season 15.
The exit: Final episode aired May 8, 2018. Perrette's tweets followed days later, citing "multiple physical assaults" as part of her decision to leave.
What was at the center of the dispute: An on-set incident involving co-star Mark Harmon's dog, which had bitten a crew member. Perrette pushed for the dog to be banned from set.
CBS's response: A vague public statement acknowledging Perrette had raised "a workplace concern" more than a year earlier and that the network had "worked with her to find a resolution."
The structural change on set: Per multiple reports, Perrette and Harmon filmed their final shared scenes on separate days throughout Season 15 and were edited together in post.
What Perrette did next: Starred in the CBS sitcom Broke (April–June 2020, one season). In 2024, she confirmed her permanent retirement from acting.
What Harmon did next: Left NCIS in 2021. Returned to the franchise in 2024 as narrator and producer of the spinoff NCIS: Origins.
What Happened in May 2018
Perrette announced her departure through a series of tweets shortly after her final episode aired. She wrote that she was leaving in part because of "multiple physical assaults" and referenced "a 'machine' keeping me silent." She did not name the person she was referring to in those initial tweets.
CBS Television Studios released a statement the same week:
"Pauley Perrette had a terrific run on NCIS and we are all going to miss her… Over a year ago, Pauley came to us with a workplace concern… We took the matter seriously and worked with her to find a resolution. We are committed to a safe work environment on all our shows."
The statement was structurally cautious — acknowledging a concern, claiming a resolution, declining to specify either. The vagueness produced the opposite of containment: fans, reporters, and industry observers spent the next eighteen months filling in the gap with speculation.
What Came Out Afterward
Over the following years, more details emerged through reporting at The Wrap, Vanity Fair, The Hollywood Reporter, and Perrette's own follow-up statements.
In 2019, Perrette tweeted that she was "terrified" of Harmon and would not return to NCIS. She did not pursue legal action.
In 2023, a Hollywood Reporter oral history of NCIS marking the show's 20th anniversary included an on-record account from executive producer Charles Floyd Johnson. Johnson described the central incident: Harmon had brought his dog to set; the dog bit a crew member; Perrette — a longtime SPCA supporter — was distressed by the incident and the dog's continued presence on set. Per the account, Perrette and Harmon stopped filming together, with overlapping scenes shot on separate days and edited together in post.
In 2024, Harmon spoke about Perrette in an interview on The Rich Eisen Show, praising her work on the show without engaging the specific allegations. He has not commented publicly on the substance of the dispute. His representatives have not responded to multiple requests for comment from entertainment trade press.
Perrette retired from acting permanently after Broke ended in 2020. She has since produced documentaries, including Studio One Forever (2023). She told Hello! magazine in 2024 that she has a deep need for authenticity that acting no longer serves.
What CBS Did and Did Not Do
The CBS response is the most-studied part of the case for communications operators.
What CBS did: Acknowledged the concern had been raised. Claimed a resolution. Restated a commitment to workplace safety. Kept the show running at full ratings.
What CBS did not do: Disclose the nature of the concern. Disclose the structural changes made on set (the separated filming schedule). Provide Perrette public cover for her own statements. Address the role of the show's lead in the dispute. Communicate directly with fans, who were the show's commercial asset.
The result was a case study in how a vague corporate statement extends rather than contains a workplace dispute. The story stayed in the press for years because the network never offered a fuller account, and the fuller account that eventually emerged came from production sources rather than from CBS itself.
Why This Case Still Matters
Three structural reasons the Perrette/NCIS case is a permanent reference.
It was a long-running, high-rated network drama. NCIS was averaging more than fifteen million viewers per episode at the time. The reputation stakes were not marginal. The vagueness of the corporate response is more striking when measured against the size of the asset being protected.
It set the template for what a vague network statement produces. A statement that acknowledges a concern without specifying what was concerning, and claims a resolution without specifying what was resolved, will not satisfy fans, will not satisfy reporters, and will not satisfy the actress. It will satisfy lawyers, briefly. The downstream cost runs for years.
It happened in the same six-month window as the broader CBS leadership crisis. CBS chairman and CEO Leslie Moonves was ousted in September 2018 amid sexual harassment allegations reported by The New Yorker. The Perrette dispute and the Moonves resignation were not directly connected, but they unfolded in the same news cycle and the same corporate climate. The network's reputational bandwidth that quarter was finite, and the Perrette case sat at the edge of it.
The Operating Lessons for Studio Communications
Vague statements extend the story. A corporate statement that does not name the issue, the resolution, or the structural changes made will be filled in by reporters, fans, and former employees over time. The fuller account always emerges. It is better to lead it than to be led by it.
Structural changes are themselves communications. If a production reorganized filming schedules to separate two actors, that is a fact the public will eventually learn. A communications strategy that assumes this kind of change stays quiet is built on a false premise.
The actress controls her statement; the studio does not. Once a high-profile cast member starts tweeting, the studio is no longer setting the cadence. The only response that works is faster, fuller, and more specific than the studio is usually willing to be.
Fan trust is a balance sheet item. NCIS retained the audience. It also retained a low-grade reputation tax that surfaces every time the Perrette case is referenced — including in the show's own 20th-anniversary oral history.
Time does not close these cases. Documentation does. Eight years on, the story is still being written, still being cited, and still being referenced in trade-press features about both actors. A faster, fuller 2018 response would have produced a shorter file.
