I graduated with an excellent master's degree from one of the western European countries. I thought it would be good for my career development to do a PhD in another university but unfortunately I now find myself in a lot of trouble. The lab I am working at has several issues and there are many deeply unethical things going on. I am pretty confident that if I leave the lab without completing a degree, the professors will try to hamper my applications to other places.
Is there anything I can do? Obviously I am no longer a good applicant but someone who (at least seemingly) "failed" first. I wish this was my fault but it is not.
To make the question clear, I am contemplating on leaving due to ethics issues, general unfairness, and repeated mistreatment of employees (not just me).
