As Joyce herself has explained, and as I reflected it in another article a couple months ago:
Joyce was working at the Economist as finance editor and Britain editor, her "dream" job. She was unaware of trans people's existence until about five years ago when her boss asked her to write an article, upon which she became personally fixated on cultivating opinions about trans people. She wrote a book in 2021. The Economist didn't want to assign her more articles on this topic (which was anyway not her area of expertise, not what she had been hired to do, and not the main thing the Economist publishes). Although she says “the Economist has been pretty supportive of me on this topic,” she took a sabbatical to work at an anti-trans organization called Sex Matters, and by 2023 she had “decided not to go back to the Economist" because "the work that I’m doing [at Sex Matters] matters too much to me.”
So, she wasn't fired from, nor pressured to leave, her job at the Economist. She says she left the Economist voluntarily to pursue her passion: anti-trans moral panic.
