Sure, but the doctors/medicine/hospitals/liability are not any cheaper.
So the healthcare isn’t cheap, but the employer is able to gain more control over their employees by tying a piece of their non employee life to the employer creating more friction to prevent people from shopping for jobs with higher pay, and the employee is getting a small tax benefit.
Yes, but the same insurance company will screw with your coverage depending on your employer.
My mom's plan randomly denied my medications all the time as a student. My current job's plan always provides coverage.
Both were the same insurance company, but she's in a different field with a more stingy employer.
