Should Amazon be the Only Business on the Hot Seat?

Apparently, the New York Times article detailing Amazon's workplace environment has piqued more than the public's interest. Thousands of people are said to have posted responses to the NYT article both in favor of and in opposition to the description of Amazon as a "bruising workplace" environment. 

And now, the government is involved. I read in this Publisher's Weekly post after the article appeared, Democratic House Leader Nancy Pelosi paid Amazon HQ a visit to check things out and discuss the Equality Act. Maybe it's just to keep them in line, but an article and a trip like this doesn't go unnoticed.

Coming to his company's defense is Nick Ciubotariu, Head of Infrastructure and Development, Amazon.com Search Experience, writing this response. 

All this public back-and-forth is interesting. In my corporate experience, I felt first-hand the pressure to perform above and beyond, and work extra hours. Sometimes this pressure came directly from management, sometimes from peers, sometimes it was internal pressure to get my job done, and be a great employee, to advance in the ranks, or at times, to just keep a job. 

I don't know how you can put only one business on the hot seat for this. I hear people from companies all over talk about being tied to their job, or their smartphone, and struggling with work-life balance. Is it fair this goes mostly unwritten, but is expected? What is your take on this? Are heavy workloads and long hours Standard Operating Procedure these days, are Amazon's employees being treated unfairly, or other?
