Final answer:
Jan Alvarez works as a sales promotion specialist, selling cable services over the phone to nonsubscribers, making her role critical to the company's sales and promotional efforts.
Step-by-step explanation:
Jan Alvarez, who works for a cable TV company reaching out to potential customers to sell cable services, is best described as a sales promotion specialist. This role involves proactive engagement with prospective customers, where the goal is to persuade them to subscribe to the company's services. In contrast to a technical specialist, an order taker, or a customer service rep, a sales promotion specialist such as Jan is directly involved with promotional activities that aim to increase sales.
Part of Jan's duties could include various tasks such as subscription procedures and possibly some level of scheduling and publicity, similar to what a part-time promotion assistant might do. Given that Jan's primary responsibility is to solicit business over the phone during the early evening, her role is pivotal in generating new sales and acquiring new customers, thereby fulfilling one of the core objectives of a sales promotion specialist.
Jan's role does not fall under categories such as clerical or office work, installation and repair, construction or mining, or being a manager, executive, or official. Instead, her job focuses on the promotion of cable services to nonsubscribers, which is central to the expansion of the company's customer base.
