Final answer:
Ursula's act of sharing her Polish cultural traditions at work is an example of authenticity, as she comfortably expresses her identity without altering her behavior, perpetuating stereotypes, or feeling othered.
Step-by-step explanation:
Ursula, the only Polish woman in her small company who shares her cultural traditions with colleagues, is demonstrating authenticity. This act reflects Ursula's comfort in expressing her personal identity within her workplace environment.
She does not engage in code switching, which would mean altering her behavior to fit in with a different culture, nor is she perpetuating a stigma or stereotyping. Ursula is not participating in othering, which would involve treating her culture as inferior or alien to the dominant culture around her. Instead, she is proudly showcasing her culture's traditional foods during holidays and, by doing so, she enriches the cultural fabric of her work environment while staying true to her identity.
