For your consideration ...
When did it become the government's business to tell private companies how to man their businesses? Are we going to set quotas? Will they dictate the number of cashiers per square feet of store?
Food for thought.
Well ....... Businesses are granted the privilege to operate in Maryland, or another State, upon registration of a business. With that, comes with the understanding of being regulated by the State. And when employees are replaced with robots or self-checkout lanes, the number of income taxpayers, and other contributory taxes/fees, are reduced. Which does not benefit the State. Now tally the total of employees lost due to "new technologies", and the State begins to take notice. And on a national level, the numbers swell greatly.
The reduction in employees by corporations is about nothing but greed, and to keep shareholders happy.
