You're right, if they'd have admitted it was because she was li/fo then she could have claimed employment benefits which they have to pay towards I believe. They were criticising her performance to avoid that.

That is was what they claimed, you are right. However that felt more like a boilerplate response meant to avoid a payout. Again, she asked for clarity on what that meant but never got a real response. I'm sure even now she didn't get an answer. She was an account executive at the end of the year, not a greeter at Walmart. She was not on a PIP and was exceeding her KPIs, according to the video. Even her boss was shocked. If they had real data to prove their point, they would have brought it up then and there. Instead she got crickets. The whole thing reminds of the King of the Hill episode where Dale gets hired to fire people.
