No but my naivety thought there would be more automation in place to reduce walking, sorting and picking up heavy things.
Granted I have not worked in a fulfilment center and my impressions are solely based on amazon's own material but they put out jobs for operatives that just stand there all day sorting small packets, moving from this to sorting incoming large pallets sounds like it would do more damage!
Edit: Thanks for the incorrect wikipedia page, how does compute resources come into play here? I'm not taking anything away from software that solves the nurses roster problem or applies simulated annealing, just merely quoting the source.
