From James Caldwell of Pro Wrestling Torch, http://pwtorch.com/artman2/publish/WWE_News_3/article_43765.shtml:
[H]ow much WWE talent earns has absolutely nothing to do with independent contractor vs. employee classification. The top 10 percent in WWE are making over $1.0 million to raise that annual average, which is irrelevant anyways. “Wrestling less than three days per week,” is misleading, as it fails to take into consideration the full-time WWE schedule where talent are on the road year-round with no break.
WWE covering rehabilitation cost is an indirect indictment of the system. It shouldn’t get that point where they need to cover “rehabilitation” costs when talent are destined to break down mentally and physically being on the road 52 weeks out of the year with no off-season. Also, the “wrestling less than three days” statement doesn’t take into consideration travel days in-between dates. Wrestlers can’t recover physically as part of their training to stay in shape to appear on TV, especially with the increased number of international dates and tours.
