I just found out that my sister has injured her arm at work. I asked her if she got hurt on the job. She said, yes and no.
Yesterday at work, she was handing some keys (I think they may have been her car keys) to a co-worker and pulled her shoulder. She says it is painful the next day.
This seems like a gray area on the job injury. She works for Taco Bell.
On the job injury?
