Wow, you guys have some great ideas going on here. I believe that Christiana makes a valid point in saying that the employee must act if they want something done.
In my opinion, employees should act if they expect to ever see any changes; maybe the employer may not see the problem, or never saw it as a problem, and so it takes initiative on the behalf of the employees to bring up the issues to their employer for the wanted changes to come about.
Perhaps if work place health, and ergonomics were promoted more by government agencies or third party agencies work place health would be a lot more common.
