Yeah this is true. But also the employer publicly firing those who sent the letter without some form of discussion also looks really really bad. People have an expectation of a CEO to have a really "mature" and controlled temperament.
This reminds me of those tiktok videos that have a spouse complaining about their significant other. They complain in public about whatever behavior, typically insignificant things, I think you can search like cleaning strike and see some of them. Even if it was 100% true, the people come of as petty, rude and disrespectful for publicly a private matter that makes then the bigger asshole. That is between spouses and has caused divorces and between coworkers or a boss employee relationship I would expect nothing less than the employee to be fired.
