Following up on my previous question (Academic Progression via Promotion vs via Recruitment), where I wanted to apply for an assistant professor position at a university where I am currently a postdoc. The HR advice then was that I cannot do that as an external applicant and that I need to apply for promotion next year. For more background please see my original question.
Last week I discovered that a couple of the potential candidates for this position are actually postdocs in a similar situation as mine, and already work for the same university. They are going to give presentations to the staff next week (This is how I knew). This implies that the HR advice to me was not accurate or something odd has happened. I contacted HR for explanation but didn't receive back.
I missed out on this opportunity due to false advice from HR which is not fair. What are my options?
