I've been in my first postdoc for a year and feel that I'm not progressing in my career. There has been communication issues with my PI, he's not very supportive of his senior postdocs, and it takes a long time to publish.
I am currently looking for new positions, however how do I address the issue of my one year postdoc, especially if I won't be receiving a reference letter from the PI?
Should I address this in the cover letter?
Also, he is quite big in the field, so are there any considerations I should be careful about, for instance applying to people he has worked with?
Would it be worthwhile to ask other PIs in the department that I have not worked with but I have been on good terms with for a reference letter?
