Your company provides several mobile productivity apps for employees so they can access the company network and collaborate while working from home, waiting for trains, and during other times when they are away from their desks. The apps work well, but lately you notice some of your employees using them during meetings and presentations to work on projects not related to those events.

You explained to several employees that this behavior can be considered rude to speakers and fellow team members, but your employees protested that they have mountains of work to do and meetings are sometimes a waste of time. Explain how to respond to this dilemma.
