While I have sympathy for your friend, nobody forced him to stay on.<p>I have a couple of friends who own air conditioning and heating companies.  They do very well now, yet they both started with one beat-up truck crawling in attics by themselves to earn a living.  Years later they have employees and do well.  They have both gone through surgeries of all kinds due to the punishment they subjected their  knees and bodies to during their years crawling in attics doing duct work.<p>I know graphic artists who have had multiple surgeries on their wrists due to carpal tunnel injuries.<p>Carpenters who have lost fingers due to unfortunate accidents.  And musicians with permanent Tinitus due to playing in loud environments for twenty years.<p>I spend my days working in front of a computer, probably 80 hours a week.  There are consequences to that as well.<p>I guess the point I am trying to make is that all activities come with consequences.  Yet not one of these people were forced to take and keep these jobs.  Let&#x27;s not blame employers for providing work people take freely.  I am not justifying negligence in the case of unsafe working conditions.  That is a criminal matter.
