Ask HN: I work for AWS. How do I encourage change for Amazon warehouse workers?

Ideally without getting fired. I've voiced some of my concerns to management but that hasn't gone anywhere. I know I'm not alone amongst my coworkers in feeling concerned for Fulfillment Center (FC, Amazon's term for their retail warehouses) employees. How can we in AWS organize and campaign for better working conditions for our FC teammates? This is of course inspired by Tim Bray's recent departure from Amazon ( https://news.ycombinator.com/item?id=23065782 ). I'm a software engineer (surprise surprise) if it matters.
