"LinkedIn wants to use their platform and tools to make a positive impact in the world, and connect under-served communities, such as youth, veterans, and refugees, with economic opportunities. The team at LinkedIn is aware of the fact that some groups of people have way more challenges than others when it comes to networking and accessing job opportunities. That's why they have built programs and partnerships to help individuals in these communities to succeed. To support refugees seeking employment, for example, LinkedIn has set up an initiative called "Welcome Talent. " They partner with non-profit and government groups in different countries to train refugees on key business skills, connect them with mentors, and help them find employment. LinkedIn is leveraging the social network that they created to make a difference for people in need. Their programs have helped individuals find new careers and set up sustainable lives after being forced to leave their home countries."
