I think the taboos are less around the law and more around trying to avoid a reputation that the company will can you a couple months after you've perhaps uprooted your life and moved to a whole new city. I wonder if the taboo will lessen in remote work contexts, where the employee is not so expected to uproot their lives for a job.
