Is there a way to get an academic job without recommendation letters? Who else besides supervisors/collaborators can be referees? I am at a stage to apply for an academic job, but can not find enough recommendation letters (3 typically). Currently, I am on my own grant, and mainly working alone on some relatively small, independent projects. Thus little collaborators.

When it comes to job application, they typically requires three recommendation letters. It there a way to get around the recommendation letter requirement? Apart from the supervisors/collaborators, who else can write those letters?
No (assuming you mean something like a TT assistant professor position). Recommendation letters are a vital piece of any faculty application. While supervisors and collaborators make good reference writers, there are lots of other people you can ask:


People who have taught you in graduate school
People you have been a TA for
The chair of your current department
The director of graduate studies of your graduate school department
Colleagues in your field, who are more senior than you, who are familiar with your research
People recommended by your supervisor (who should be ashamed for letting you get into a situation like this)
