After Darren Bossley suffered a job-related injury to his left hand and couldn't perform his regular job, his employer assigned him to alternative duties, which consisted of completing coursework for an electrician's apprenticeship. Bossley claimed that he was unable to complete the hours due to severe pain; however, his treating physician released him to return to work because the physician believed that Bossley was able to perform in this alternative work arrangement. Bossley was terminated from his job for failing to complete his work hours and for not reporting to work. As a result, his employer's workers' compensation insurer refused to pay disability benefits. Were Bossley's workers' compensation claims wrongly denied?
