If you have a progressive corporate tax rate, you ģive incentive to split companies, making them less efficient and less competitive vs foreign companies, as well as making it easier to dodge quotas. Making them less competitive will have the net effect of higher unemployment.
Tax is a trivial issue compared to other reasons for automating work, i.e. Having robots. Tax isn't why Amazon warehouses are full of robots and virtually empty of humans or why automobile production lines are highly roboticized.
At a simplistic level, consider basic arithmetic. A skilled worker might get paid 50,000 a year, plus the cost of benefits. This would make the direct cost at least 60,000 and usually more. This ignores absenteeism, productivity issues and quality control for when the worker is sick but still comes to work, or is hungover or depressed, etc.
Now take a robot that costs 250,000 to buy. You need a service technician, but that cost is spread over multiple robots. Interest at 5%, and that's high in today's climate for a large company, means interest costs of 12,500 a year. Add 10,000 for the technician. Add 25,000 a year to pay down capital cost, assuming replacement every 10 years.
Already the business is saving over 10,000 a year. Now realize that this robot can easily work two shifts! 7 days a week. It doesn't take coffe breaks or time for lunch. It doesn't get paid overtime. It will never unionize and go on strike. While it will need monitoring and occasional maintenance or repair, it will usually be far more precise than any human, it will not get distracted or pissed off or hungover. You could double the cost per robot and still be making a huge gain.
My numbers are arbitrary and intended for illustrative purposes. However, considerations like this are what drive roboticization. Tax issues, such as writing off the interest on the robot and/or depreciating the capital asset also play a role, but in most cases the economic/productivity/quality control gains from automation are such as to dwarve the impact of variations in tax rates.
A more obvious and plausible effect of creating different and higher tax brackets for companies with lots of employees is to cause businesses to create multiple companies. Say the tax hike kicked in at over 1,000 employees. Then a business might set up separate companies, each having no more than 1,000 employees, with each company being a wholly-owned subsidiary of the 'real' company. This idea of having multiple corporate entities for financial reasons, including tax, is already widespread
