Even the report is a bit misleading, comparing Tesla's yearly rates to the same-year averages paints the picture that Tesla got an additional 15% more risky than the industry in one year. About a quarter of the y/y change in the industry average between 2014 and 2015 is apparently residual[0]. There are only three points, but the residuals on the slope of Tesla's TRIR are lower than the residuals on the industry average [1]. What this basically shows us is that Tesla hasn't been a company long enough to establish a trend, upward or downward, of workplace injury. Worksafe Inc.'s report claims that Days Away, Restricted [activity], and Transfer[red] (understandably [given how inconsistent OSHA themselves are about what it stands for] misquoted as Days Away Transfer Rate) is a better indicator of rates of serious injury, but it's obvious to a layperson that days off, even on a 300 form, are discretionary. It could just as easily be the case that Tesla workers are encouraged to take days off for more minor injuries.
