What makes it so great?

Pep rallies aren't just for high-schoolers. At Atento -- the customer relationship management subsidiary of Telefónica Group (also on this list) -- managers host an "Atento Rally" once a year, where teambuilding activities are divided into four themes: sports, artistic talent, theatrical events, and general entertainment. The company also has the Atento Academy, a training program that involves all levels of employees, from executives to "business professionals." Programs like these keep the staff happy; an employee says, "The work environment here is great. I have found people that have helped me to grow, both personally and professionally."
