Minnesota recognizes a repetitive work injury as a compensable work injury.  That means if the wear and tear on your body that your work environment places on you causes a work injury, a specific injury, then you need to report the claim to your supervisor.  That is a work injury under Minnesota law.  You would be entitled to wage-loss benefits, permanent benefits, and medical benefits because of that injury.

Typical things we see are carpal tunnel, through the use of vibrating tools, or shoulder injuries.  Just using heavy shoulder work can wear out your body.  So yes, those are work injuries.
