As for now Supreme Court treated termination of contract of employment as justified if at least one of the causes was justified. As per judgement of the Supreme Court dated 14th of April 2016 (II PK 140/14) it is required to check proportion between justified and unjustified causes. To treat termination as justified, justified reasons should be in significant proportion comparing unjustified causes. Please note, the judgement does not concern situations when employer points to several minor issues to show one justified cause. The above concerns several causes when employer counts that at least one cause is justified. As a result it is worth to resign from causes employer is not sure it is justified.
