The document describes a scenario for assertiveness training involving a construction worksite. A newly hired worker, Juan, is ordered by his supervisor Alan to complete a task without a safety harness. Juan refuses, citing the need for protection. Three co-workers pressure Juan to do the task without a harness. The scenario continues with Juan unable to properly use a harness and being threatened with firing if he does not do the job without one. The role players are then coached on how to respond assertively while refusing dangerous work, as workers have a right under OSHA to refuse imminent dangers.
