A Calm Person Works Calmly

Any firm in this country is motivated by the consideration of Man's well-being. But Man is also a productive force that keeps a business going. A thoughtful approach is needed not to divide the two concepts of Man as a productive force and as the main concern. Special efforts are also needed to ensure that the principal goal - Man's well-being - is the focus of attention every day and every hour.

A special social-psychological service has been set up in many firms to help make its principal goal a reality. The service is a laboratory and a group of psychology experts. The laboratory carries out experiments, using visual display units, to study the ability for team work, the characters of the working people and their manager. Other methods include questionnaires, polls, and specially-oriented studies. They produce either immediate results or give recommendations a bit later. Fatigue is studied from every angle - the nature of work, age, sex, and working conditions. And the recommendations vary.

In one case it is an additional 15-minute break in work spent in relaxation room. Sitting in an atmosphere of quiet, coolness and semidarkness people hear a soft voice talking about self-training. This is followed by watching a beautiful scenery on the screen to the accompaniment of music. Fifteen minutes of this relaxation can make a person feel as if he has been away from work for several hours.

In another case physical exercise, some sitting-up exercises may be recommended, or a person may be advised to go to refreshment room and have a glass of specially-prepared cocktail of juices.

There are certain monotonous, mechanical jobs in which only part of the brain is used. According to the psychologists, the other part can and should be used for the general development. So a psychologist would go to such people and talk about new films, plays or books. He does his best to help workers overcome stress situations.
Notes:

fatigue – усталость

scenery – пейзаж

to overcome – преодолеть

Отримавши листа з дитячої кімнати міліції, директор школи кричав Славкові: «Така пляма на нашій школі! Негідник!… Честь школи тобі не дорога,
можеш забиратися геть!»
Як ви вважаєте, чи має він рацію? Що, на вашу думку, важливіше — власна честь чи честь колективу? А можливо, це має бути взаємопов’язано?
