We've all worked in an environment where the employer forbids the use of personal mobile devices. Some companies set very strict rules about using smartphones, tablets, or any other handheld devices at work. We can argue that, in many work environments, this causes more harm than good. First off, human nature is such that we rebel against restrictions, especially those that do not make sense. Employees often sneak off somewhere to look at their phones or openly use their work computers to check their personal email, despite repeated scolding from the manager.
