"Earlier today, CBS This Morning (video clip not yet available) mentioned that Mayer had viewed remote workers' VPN usage, only to discover that employees were not using the virtual private network when and as often as they should be. If true, this would sound alarm bells for any executive, especially one at the helm of a company facing as many challenges as Yahoo does today."
If that is true, the correct approach is to talk to those employees specifically, and not punish all remote workers. When I work from home I use a local environment because the VPN is slow. I only connect when absolutely necessary.
Better than what I had initially though from the headline: That she had actually looked at the logs of how they used it during the day.
