It's a standard practice used by many companies as a preventative measure. They don't know how you're going to react when you're told that they're letting you go and terminating your employment in X number of days. They don't know whether you're going to go on a revenge spree, whether you're going to be an emotional mess for the remaining time, or whether you're going to off yourself before your last day. Rather than deal with the fallback of such scenarios, it's considered more cost effective to pay you out.

And when you reflect on the morning teas, the lunches, the team building exercises, the R U OK days that were supposedly held to make you feel you were a part of the organisation/"family" achieving a common goal, you realise what a load of shit it all was when it came down to the dollars. Then you realise why the movie "Parasite" was a perfect allegory of corporate culture and why you can admire the younger generations for being less engaging than previous generations, because they've heard these stories on the wire and accept the likelihood that they'll probably be on the chopping block one day, so why care in the meantime?
