Traditionally people go to work. Sometimes it takes them hours to get to their offices. What a waste of time! So nowadays more and more people prefer to work at home. It seems much easier. You are not afraid of being late for work because of traffic jams or car breaks. You choose when to start working and when to stop. You may take a cup of coffee without haste and then turn on your computer There is no boss behind your back, in fact you are your own boss. So there are a lot of pluses, but also some minuses in this situation. It is difficult to manage your time effectively. When you are at home there is always a lot to do, and if you are not a very well-organized person you will postpone your work until it's dark outside. Then you have to work at night when other people have a rest. Besides, if you work at home you feel lonely. You don't see your colleagues, you don't exchange ideas with them, you feel like you are on a desert island. Some people are born team workers, when they talk to other people it inspires them, and they can produce brilliant ideas. For such people working at home is out of question!
