This is such a nothingburger of a point that gets trotted out every time these discussions happen. No business I have ever worked for in my entire career has given a wet shit about the "regulatory burden" of hiring. We hire the minimum number of people we think can do a given job effectively, and then products end prices are based on those expenses, raw materials, with an amount on top for profit. The regulatory and compliance burden is an expense, sure, but it was an expense the second we hired one person. The work is more for 150 people vs 1, sure. But that's literally why you have an HR department, that's their entire reason to exist.

If your business can't employ people without abusing them you don't belong in business, period, paragraph. Stop bellyaching about the work you have to do to run a business and do your fucking job.
