I don't know whether to start crying for the poor downtrodden work force, or figure out a way to replace them machines. While machines won't appreciate having a job in this economy they sure won't complain about it either.
I have had my share of tough jobs and there is no great trick to handling it. You do the best job you can while finding another job.

This is the practice at every warehouse and Amazon will loose this suit(there is precedence). In addition they commonly run off employees after their 55th birthday. That suit will be filed shortly.
