Fernanda has worked with her officemates for two years. When she started working she was very careful to return from every break on time and to keep meticulous track of her time. Over the last month she has spent more time at breaks with her colleagues who encourage her to write down the proper amount of time for the break regardless of how long they were away from their workstations. "Everyone does it," one of her colleagues said, and the others agreed. Fernanda does as her colleagues have told her to do. What social factor(s) have affected her ethics?
