You would assume wrong, many (asshat) employers require them, so much that I actually have to screen that kind of sillyness when interviewing. Works a treat to filter out toxic workplaces, but exists nontheless.

As for leaking assets, maybe it does not affect the company at large, but that literally does not matter for this discussion. It will definitely affect your relationship, most often negatively.

And in any case, my usage of assets was clearly general, substitute the example for "clicking on the wrong stored tab while screensharing" can just as well lead you to leaking a plan.
