In actions brought under this article, the question of whether the employee was guilty of contributory negligence or assumed the risk is a question of fact and at all times, regardless of the state of the evidence relating thereto, shall be left to the jury. The fact that the employee was guilty of contributory negligence shall not bar a recovery, but the damages shall be diminished by the jury in proportion to the amount of negligence attributable to the employee.
