The constant restructuring at Uber - is it sustainable?

Reading about the latest Uber layoffs, and it's becoming a pattern. They've been trimming down various departments for a while now, from Postmates integration to now the people division. While I understand businesses need to adapt, this feels like a constant state of flux. Are these strategic moves actually making the company stronger, or is it creating a culture of instability and fear? I'm starting to worry about the long-term impact on employee morale and retention. When will people feel secure? It's hard to invest your best work when you're constantly anticipating the next 'necessary change'. What are your thoughts on this cycle of layoffs?
