Amazon CEO gives employees a harsh wake-up call
The online retail giant is undergoing a major change in its work culture.

Amazon (AMZN) has been on a mission over the past few months to revamp significant elements of its work culture, which has garnered sharp criticism.
Earlier this year, Amazon began requiring corporate employees to work in the office five days a week after allowing them to only do so three days a week under the previous in-office mandate.
