This is simply not true in most US States. I wish people would stop spreading this sort of misinformation.
Just because an employee is terminated “for cause” does not mean they will be denied UI. In most US jurisdictions, denial of UI requires malfeasance, insubordination or gross misconduct on the part of the employee.
Kind of odd that I had to scroll this far down to see this.
It’s obvious that OP’s employees don’t feel they’re treated well and probably don’t like them personally. Since he’s the kind of employer to spy on his workers and electronically eavesdrop on their conversation, they likely have good cause.
