An employee has a responsibility to the employer under to (revise to country legislation if needed):
Work safely by following all safety directions of supervisors or managers
Work in a manner that is safe to fellow workers. An employee cannot refuse to follow safe work practices that have been set up in the workplace, eg. refusal to wear goggles and a mask when using corrosive chemicals, like oven cleaners, is to behave in a wilful and dangerous manner which will endanger your health
Report any injury or illness as soon as possible to the supervisor or manager
Give workers’ compensation claims to the supervisor or manager. Workers’ compensation usually will not be paid if the person was behaving in a dangerous manner (serious or wilful misconduct), if the person broke the law, or the injury was self-inflicted
