But regulations don't say "fire this person". They're normally far more high level than that, like, "when something bad happens, trigger a corrective and preventative actions process and write down what you found and what you're going to change, if anything".

Effective regulations very much do put the employer on the hook, no way to accept something like "voluntary employee risk-taking" outside of in some cases not looking for it as hard as they could. Employers are at risk of getting fined for tolerating (or worse) employee risk-taking and if those fines are sufficiently high they will certainly tell the employee "stop doing that that or else". And the last stage of "or else" certainly is getting fired, perfectly in line with other worker protection laws that might be in place that would otherwise prevent that getting fired.

You seem to be agreeing with me. Companies don't have to fire people due to regulations. They may do so, or they may do all sorts of other things.

They're far more likely to fire people based on board pressure or PR. Regulations are the least impactful things here.
