According to Abraham Maslow's Hierarchy of Needs, a newly employed accountant at a Nigerian audit firm is primarily motivated by receiving a competitive salary that covers rent, food, and transportation. At which level of Maslow's hierarchy is this employee operating?

Physiological needs are the most basic level of Maslow's hierarchy and include food, shelter, clothing, and transportation — all of which are fundamental survival requirements. The employee's focus on salary to meet these basic living expenses places them at the physiological level, not safety or higher-order needs.
