In this photo, the employer has asked the employee to erect a ladder jack, quite common, in which the left and right vertical sides are elevated about a foot at time by the worker raising the walk board by operating a foot lever. But instead of a "stage" or "pick" to work from, the employee has given the worker a ladder to walk on: tricky and hazardous if not impossible. In addition, the ladder is not equipped with fall protection to keep the worker from tipping over backward even if he or she could walk and work from it. Is there anything else wrong here
