Angus is hired by Harriet to sell ice cream occasionally when Harriet is not able to take care of sales. One day, he gets stuck in the small cooler room in the van for half an hour because of a faulty door. He suffers pneumonia as a result. Harriet had known about the faulty door but failed to get it repaired or mention it to Angus. Advise Harriet whether she is responsible for Angus under Employment Law.
