Working is making desirable changes in the environment through human activity. Work can be both physical and mental.

In an economic context one speaks of labor. A distinction is made between paid and unpaid work. Unpaid work for third parties that does not involve coercion is called voluntary work. Unpaid work for third parties that involve coercion is called slavery. Labor in people under the age of 12 is called child labor.

A distinction is also made between employers and employees. An employee is someone who performs paid work. An employer is a natural person whose work creates paid work for others, or a legal person employing employees.

Work is a productive activity, which implies the implementation of rigorous and methodical, intellectual and / or manual knowledge, to produce and dispense goods and services in exchange for compensation, monetary or not, an important subject of study both in the social sciences (sociology, politics, law, economics) and abstract and natural sciences (physics and geography).

The most appropriate definition of work, even from a social point of view, is the one written in many economics texts: “Work is that activity which is not an end in itself, but which tends to procure other benefits”.

It is a useful service that is rendered to society, and provides for the systematic concession to the public of one good in exchange for another, in the form of compensation that is not always monetary. In the modern world, work is carried out with the exercise of a trade or profession and has as its purpose the satisfaction of individual and collective needs. From a legal point of view, subordinate work is distinguished from autonomous and para-subordinate work with intermediate characteristics between the first two.


A variety of training courses are available, most of which are available for free or at a low rate. For example, you can learn programming (see below), learn everything about cryptocurrency, e-commerce, marketing, learn web design, internet, e-mail, social media, projects, big data, data centers, b2b, b2c, HR, etc.

A programming language, in computer science, is a formal language that specifies a set of instructions that can be used to produce output data: it can be used to control the behavior of a formal machine or an implementation of it (typically, a computer) or in the programming phase of this through the writing of the source code of a program by a programmer: a programming language is considered to all intents and purposes as such if it is Turing-complete.
