Right, but in this case, exposure is a work requirement, which is a bit different. While an employer isn't going to require tobacco use, work involving asbestos exposure is still a thing (removal perhaps), and an employer knowingly or negligently requiring work activity without both risk disclosure and supply of proper safety equipment would face legal action.

Hence, if mandatory workplace use of AI inflicts harm, then I could imagine things playing out similarly. The damage slowly accumulates, may or may not be noticed in time, becomes difficult to pin down on a past employer, and when you finally realize you need to sue for damages, both the employer responsible and the system are rigged to drag out the process until you're hopefully old and dead before you have a chance to win your case.

...oh.
