We would like to recommend a publication by Józef Wieczorek:” Academic mediator as a measure against mobbing in the academic world”, which is available (in the Polish language version) at this link:
http://www.pum.edu.pl/__data/assets/file/0007/25864/Mediator_akademicki.pdf
It should be noted that since the publication of the volume there have been some important developments, including, the appointment of two academic ombudsmen.
