There are few chief executive decisions that drew more attention this year than Yahoo (Fortune 500) CEO Marissa Mayer's work-from-home ban. The policy was initially seen as highly controversial and had a lot of people upset because of its perceived lack of flexibility. ,
Despite the criticism, Mayer defended her decision to Fortune in April and said that the move was "wrongly perceived as an industry narrative." Mayer said she needed employees to work in the office to encourage collaboration and innovation from workers. So far it looks like her controversial move may be helping the business: Yahoo's stock is up more than 100% since Mayer took over in 2012.
