So, 36 people (at present, anyway) sign a letter. What in the flying frig is that actually supposed to accomplish? There's nothing really actionable here; you've got the nothingness of "that leadership commit to transparency, clear communication, and real accountability."
Are these people going to actually do anything - quit in protest, sabotage, what? No, they are going to whine, and keep drawing their very lucrative salaries and benefits. Put up or shut up.
