Miguel, being the head of marketing, oversees the marketing department, which suggests that Priya, as a senior marketing strategist, is part of his team and reports directly to him. Javier, a sales associate, works with Priya on projects that involve both sales and marketing, indicating that he is likely part of the sales department and collaborates with the marketing department on joint initiatives. 

Priya cannot authorize Javier to run a marketing campaign without consulting Miguel, because, as the head of marketing, Miguel is in charge of all marketing activities and decisions. As Priya's superior, he would need to approve significant actions like launching a new marketing campaign, especially since such a campaign would likely fall under the marketing department's purview and could impact the company's overall marketing strategy. Moreover, since Javier is from the sales department and collaborating on cross-department projects, his role would be guided by the decisions made by the heads of his own department and the marketing department, with the latter being Miguel's responsibility. Therefore, Priya must seek approval from Miguel before granting Javier the authority to initiate any marketing campaigns.
Miguel has been appointed as the new head of marketing. Priya reports to Miguel as a senior marketing strategist. Javier is a sales associate who works with Priya on cross-department projects. What is the professional relationship among Miguel, Priya, and Javier? Can Priya authorize Javier to run a marketing campaign without consulting Miguel? Respond briefly.
