SAN FRANCISCO, Oct 27 (Reuters) - Amazon is planning to cut as many as 30,000 corporate jobs beginning Tuesday, as the company works to pare expenses and compensate for overhiring during the peak demand of the pandemic, according to three people familiar with the matter. The figure represents a small percentage of Amazon’s 1.55 million total employees, but nearly 10% of the company’s roughly 350,000 corporate employees. This would represent the largest job cut at Amazon since around 27,000 jobs
