Leaks, funnily enough, from just shy of 4e 40k. Especially as a reaction to the leaking of an entire late-in-the-process playtest tyranid codex (the 3.0 book, the one that, iirc, first introduced rending, back when it was auto-wound and ignore armor on sixes. In the play test book you could give it to entire units of gaunts, it was pretty sick). Admittedly, I suppose that was a while ago, now, so things have almost assuredly changed since then. Huh. Time does have a way of slipping past us old geezers.
Individual employees are under considerably greater compulsion to work regardless of their feelings for or treatment by their employers. After all, if the employment relationship falls through, the employee is at risk of going without food, shelter, and medical care if they cannot find other employment quickly. The employer rarely if ever faces the same sort of existentially catastrophic consequences, while simultaneously usually having a far easier time finding a substitute.
Given the difference in relative power & vulnerability involved, the moral imperative should, if anything, be far more heavily levied against the employer, to disincentivize systemic institutional abuse.
