Why Kelly - Since 2011 we have placed over 16,000 Veterans

Need More?

Kelly applies targeted recruiting initiatives to the Veterans population (in all stages of transition) by aligning customer defined requirements with military skills and experience.  The transition from military to civilian life can be stressful and complex for veterans, and our staff is trained to assist in this transition.  Unlike our competition, Kelly places these resources without geographic or industry constraints, offering our customers and our employees greater flexibility.  Kelly has a wide variety of local opportunities, for Veterans and their spouses, within our workforce solutions as well as national recruiting programs on behalf of our customers.  Kelly’s leading placement opportunities for Veterans are within Information Technology, Engineering, Science, Light Industrial and Call Center.

Our specially trained Veteran recruiters are armed with a number of tools to help Veterans obtain roles that match their potential including skill translation tools, leading Veteran- centric job boards and Veteran/spouse social media networks, among others.

Through Kelly’s vast branch network, we are closely located to the majority of major military installations across the United States.  Kelly recruiters participate in onsite and virtual military career fairs as well as advertise through local and national Veteran job boards.  In recent years, over 150 Kelly branches have worked directly with their local military installations to recruit spouses and transitioning personnel.  These teams not only engages with transitioning talent from local bases, but also have a strong focus on Veterans in areas where the military has identified high Veteran unemployment. This approach ensures that military talent is engaged and shared across the centralized military recruiting team and documented in a centralized database, so that other Kelly locations can benefit from hiring or relocating this valuable pool of talent.

Our focus on military recruiting is a win on multiple levels. Kelly gains top talent with the skills needed to excel; our clients receive the benefit of that talent to help them compete in an ever challenging business landscape; and Veterans receive gainful employment in line with their skills and abilities to ease the transition to the next phase of their lives.
