As used in the Workers’ Compensation Act, unless the context otherwise requires, “injury by accident arising out of and in the course of employment” shall include accidental injuries to workers and death resulting from accidental injury as a result of their employment and while at work in any place where their employer’s business requires their presence but shall not include injuries to any worker occurring while on his way to assume the duties of his employment or after leaving such duties, the proximate cause of which is not the employer’s negligence.
