I know that retirement age is 67 here in the US but...

what if one works at the same company for 30 years. Can they not retire from that job, regardless of their age after 30 years of working there?

For example, if I work at this job I'm currently at for the next 30 years, I'll be 61, with 30 years of service. Can I not retire from said job?
Or is this where you only get half of your money?
