Final answer:
Marcela should start her request by aligning the need for safety equipment with company values and end with motivation showing the benefit to overall company welfare and productivity.
Step-by-step explanation:
Marcela can start her persuasive message by immediately addressing the crucial need for safety measures in the workplace. A compelling way to begin might be, “As a vital part of our company's commitment to employee health and the success of our operations, I urge us to consider the critical importance of providing face masks and aprons to our packaging department staff.” This opening acknowledges both the company's values and the practical benefits of the request.
To conclude her message with motivation, Marcela could assert, “By equipping our team with the necessary protective gear, we not only enhance safety but also demonstrate the company's dedication to its employees, fostering a more productive and positive workplace.” This closing statement aims to move her supervisor to act by linking employee protection to overall company welfare and productivity.
