Toxic boss? Red flags?

I was recently hired for a mid size company. My salary is not only market value rate but also what I deserve based on my experience and expertise.

The first day on the job, my boss said that she expected me and another colleague who was also hired the same time, to work more hours because we are getting paid more than others on the team.

WTH?! I ignored her and decided to work the hours I am paid and that’s it but it’s not my problem the company isn’t willing to pay their employees and also they didn’t negotiate their salary. So far she hasn’t said anything but it really irked me that she even said that.
