Thank you for your question.
Unfortunately, unless this behavior is motivated by discriminatory purposes (i.e. based on race, religion, age, sex, etc.), it is illegal. While employees can be required to work overtime, they are entitled to overtime paypursuant to federal and/or state laws as long as they are not exempt employees, which doesn't always necessarily mean that they are salaried.
Emotional distress claims are actionable, but to be successful, the employee must generally show that the employer's actions are so extreme and outrageous as to go beyond all bounds of decency. This is a harder standard to prove than it sounds. At first blush, the statements your employer has made do not seem to live up to this standard. The abuse would have to be extreme and outrageous, almost unbelievable.
Yes, unfortunately, that is what I am saying.
