Companies are made of individuals, and individuals can be shady and crooked. In a vacuum, it’s probably somewhat as likely that the person getting fired and the company doing the firing are scumbags. I’d personally argue that companies have more of a reputation to uphold for profitability reasons, and will therefore be incentivised to act less scummy than individuals.

In this case, the company has nothing to gain no matter how they sever the contract. They’re simply getting rid of an employee who was either costing them money, or getting rid of many employees at a time to navigate a difficult economic situation.

The person making the TikTok on the other hand has a lot to gain from making a controversial and attention-grabbing spectacle out of this.
