Which of the following would NOT be considered harassment?

Harassment in the workplace generally refers to unwelcome and inappropriate behavior that creates a hostile, intimidating, or offensive work environment. The correct answer identifies a scenario that would not fall under this definition because having a conversation with a fellow worker over lunch typically implies a mutual relationship and does not involve any form of intimidation or inappropriate behavior.

In contrast, making rude comments to an uncomfortable employee or making sexually suggestive remarks to a co-worker both clearly reflect disrespectful behavior that can create a hostile environment. These actions can lead to feelings of unease or discomfort, thereby categorizing them as harassment. Calling an old girlfriend to hang out, while potentially inappropriate depending on the context, does not inherently involve the workplace or a power dynamic that characterizes harassment. Thus, it is the nature of the interactions and the context that distinguishes everyday conversations from harassment.
