Investments in Worker's Technlogy - I need a correction please. Advances technologies in work office have increased the worker's production, because workers are more quickly in their work and they can spend more time in front of the desk. For example, the photocopy machines save worker's time in making copies and documents; the introduction of the email making the comunications more fast, convenient and cheap, and they eliminate the frequent worker's meetings. All this making these types of investiments a big pay back for business choices. Instead, the technologies in work office causing also a bad effects for physical problems in workers and it can reduces their productivity. In fact, spending all the day in front of the computer, causing pain to the eyes, the back and the neck. For trying to resolve these bad effects and incresing productivity and health, it has been suggested to have a break where the workers getting up and walking around for five minutes every hour, to have a meal out the office and to use ergonomic chairs and keyboards in their desk places.
