You can't really be surprised by layoffs at Pfizer. They've demonstrated over and over again how little they think of their employees and how disposable they find us to be.
The company has literally laid of entire teams just to make sure the shareholders are kept happy. Of course, that's just short term happiness, because we all know that layoffs can't solve the company's issues long term.
Maybe if we started innovating again, we could see some long-term results. Or if set a clear, long-term vision for the future. But no, the geniuses at the top will stick to layoffs.
