Dismissal
Fair reason, fair process. Both, every time.
Every dismissal in South Africa is measured against two questions: was there a good enough reason, and was it arrived at properly. An employer who has one without the other loses, and an employee who has neither does not win by wanting to.
The four grounds
There are only four, and one of them is not really a dismissal.
This part of the law is identical whichever side you are on, so it is set out once.
Misconduct
The employee did something. Theft, dishonesty, insubordination, absence without leave. The employer must show the rule existed, that the employee knew it, that it was breached, that the rule is applied consistently, and that dismissal is an appropriate sanction for this breach by this employee.
Incapacity — poor performance
The employee cannot do the job to standard. The employer must show the standard was communicated, that the employee was given a fair chance to meet it with support, and that no alternative short of dismissal was workable.
Incapacity — ill health
The employee cannot attend or perform because of illness or injury. The nature, degree and likely duration matter, and so does whether the work can be adapted. Dismissing somebody for being ill without investigating adaptation is where most of these fail.
Operational requirements
Nobody did anything wrong. This is retrenchment, it runs under a different section with a consultation process of its own, and calling it anything else does not change what it is.
Four things, twice each
Where these are actually won and lost.
The hearing is not a formality, and it shows when it is treated as one.

Consistency is the ground employers most often lose on.

The same advice to both of you
Write it down while you still remember it.
Dates, who said what, who was in the room, what was handed over and when. Eighteen months later the arbitration will turn on details neither of you can recall, and the party with the contemporaneous note is believed. That is not a legal principle, it is just what happens.

Send us the notice, the minutes and the outcome.
Whichever side you are on, those three documents tell us most of what we need to say whether this is worth running.
