Answer: Employee complaint
Step-by-step explanation:
From the question, we are informed that last month, Mishika, a secretary in a large university, complained to OSHA that the air in her office made her sick and that she could see green mold in the ventilation system.
We are further told that she had been treated for breathing problems 4 times in the past year. An OSHA inspector arrived at the plant this morning to provide employee complaint. This is because of Mishika's complaiint.
