On that note, here are some reasons why working from home can be just as, or more, productive than working in an office environment:
1) No Random Interruptions From Your Coworkers
Working from gives people long stretches of uninterrupted time to be creative and productive. No one is stopping by your desk, no one is throwing a Nerf dart at you, or being overly loud one cubical over. The biggest distraction is an email, or Skype ping, which, if you're really in your work-groove ("flow"), you can turn on and off notifications and respond on your own time.
2) Flexibility to Step Away and De-stress
Sometimes we get stuck on a particularly difficult task, and the best thing we can do is step away from it a moment and come back with a clear and focused mind. Working from home gives you the opportunity to do just that without worrying about disturbing others around you, or becoming a distraction yourself. Also taking mini-breaks when you need to will make your overall work much more productive.
3) No “Michael Scott” Meetings
Almost everyone is familiar with the character Michael Scott from The office, and his famous impromptu meetings that pull the whole office away from their actual work. Surprisingly these types of meetings are coming in many companies. When you work from him, If you're needed in a meeting you're able to call in and take care of business pretty quickly. You don't have to worry about getting pulled into whole-office meetings that really have nothing to do with you, and only waste your time that could be better used otherwise.
When you work from home you typically have less interruptions, which can lead to higher productivity. Distractions are present in a home office environment (T.V., Social Media websites, etc.); however, these are voluntary distractions (e.g. distractions that you can choose to engage in or not), while many of office distractions often come without warning.
So is working from home more productive? It might be. There are many factors that play into someone's productivity (personal habits, level of tiredness, interest in the work at hand, etc.), and working from home can't be the solution to all of them. However, it certainly is a way to maximize productivity by getting rid of many typical office distractions.
