Final answer:
Delta seems to employ arousal theory, self-efficacy, and social motives in motivating employees, through optimal challenge levels, belief in capabilities, and fostering a supportive culture.
Step-by-step explanation:
Delta seems to be utilizing motivational theories including arousal theory, self-efficacy, and social motives, such as the need for achievement, affiliation, and intimacy. Arousal theory suggests that we are driven to maintain an optimal level of arousal, neither too bored nor too stressed, which can be seen in how Delta may manage employee workloads and environments. Self-efficacy, theorized by Albert Bandura, states that if employees believe in their capabilities, they are more motivated and likely to take on challenging tasks and persevere. Lastly, Delta may encourage social motives by fostering a culture that recognizes achievement, promotes positive interactions (affiliation), and seeks meaningful relationships (intimacy) within the workplace.
