Was Sari bullied? Why or why not?

Sari works in a large mining operation in Saskatchewan. She has been with the company for a number of years and is currently a heavy equipment operator.
As the mining business continued to grow, and as the workforce became more diverse, senior leaders in the company also determined it was important to ensure that the workplace did not engage in discrimination or harassment. Training was initially done with everyone, and then the company also created ongoing discussion groups with the managers to talk about discrimination and harassment and reinforce the role they play.
Shortly after the initial training for all employees, Sari approached someone in HR to report that her boss (a man) had bullied her on several occasions. An investigation was undertaken to determine what had occurred, what had been said, and what the manager had to say. Part of the investigation included conversations with Sari’s coworkers to see if they had experienced any bullying.
