Personal life and work life imbalance: As it involves work being done in the same physical space as where most people typically go about their personal lives, it is inevitable that work will be invasive in your personal life or vice versa. This means that maintaining harmony between work life and personal life is crucial to the success of virtual work.
I doubt many companies like or prefer that employees work from home. We allow the policy in order to be able to attract employees who would otherwise go elsewhere. We are heavy users of Slack, Confluence and other collaboration tools that make working at home more productive, but they cannot replace the serendipitous interactions that occur while hanging out by the nitro-coffee keg. - Manuel Vellon, Level 11
