The claimant alleged that he suffered a significant, disabling knee injury while carrying an air conditioner at work during the early hours of his shift. The claimant worked his entire shift, performing his full work duties for the remainder of his day. The claimant testified that he reported the work injury to a representative of the human resources department upon his completion of the shift. We offered testimony from three members of the human resources department who all contested the claimant’s testimony. Additionally, we offered video from three cameras located in the facility which showed the claimant moving freely and, furthermore, showed that the claimant did not enter the human resources office suite on the day of the alleged incident. The judge found the claimant and his doctor not credible and further found all of the employer’s witnesses and evidence to be more credible and convincing. The claim petition was denied and dismissed.
