On that you are 100% wrong. I can tell you from first-hand experience as a corporate consultant who worked in many states there are a lot of states that stipulate if you work some predetermined time duration in that state then you owe that state income tax regardless of what state you are paid in.
Here’s my “authoritative” source: https://www.cpapracticeadvisor.com/tax-compliance/article/12405584/the-tax-travails-of-employees-crossing-state-lines
“However, aggressive state and local taxing authorities recently began pursuing high-profile taxpayers like professional athletes and entertainers who work at multiple locations. Now this so-called “jock tax” is being applied on a wider scale to traditional business travelers.”
Good luck getting any volunteers next time.
