Does this glassdoor post apply to engineering/creative roles too? I don't think that destroying morale is productive, but I could at least understand what they were trying to do if this only applies to their warehouse/fulfillment/etc operations: if you don't stuff enough envelopes fast enough, or encode and annotate movies fast enough, or deal with customer service calls efficiently enough, it can make sense to replace you with someone who does.
