Here (seemingly) endeth the lesson; unfair dismissal defined

“A dismissal may be:
Harsh – because of its consequences for the personal and economic situation of the employee, or because it is disproportionate to the gravity of the misconduct;
Unjust – because the employee was not guilty of the misconduct on which the employer acted; and/or
Unreasonable – because it was decided on inferences that could not reasonably have been drawn from the material before the employer.
