Dear, listening to your story, it should not be a work-related injury. Although you had an accident at work, your diagnosis was potassium deficiency, not man-made injury, but the lack of trace elements in your body, and the dispute was only the fuse. As for absenteeism, since it is not a work-related injury, it is of course absenteeism. In this case, you can be fired. You can find someone to bend the rules and call it sick leave, so that you won't be fired. Above, although I am sorry for your hospitalization, the fact should be like this. I wish you a speedy recovery! !
