Final answer:
Social networks have a dark side that includes increasing workplace discrimination, fostering extremism, and spreading misinformation, which can be damaging to an organization and society.
Step-by-step explanation:
The dark side of social networks is that they can increase workplace discrimination, propagate extremist views, and spread misinformation, potentially undermining democracy and fostering division. While social networks do facilitate connections and provide emotional support, allowing individuals to challenge their beliefs and prejudices, they also enable in-groups to form, which might show favoritism and exclude others. This can promote an organization's internal politics and cause tension. Furthermore, the unchecked spread of fake news and hate speech on social media platforms can significantly impact society at large, as was evident in the role these platforms played in the manipulation of voters.
