Hierarchical organizationA hierarchical organization or hierarchical organisation (see spelling differences) is an organizational structure where every entity in the organization, except one, is subordinate to a single other entity. This arrangement is a form of a hierarchy. In an organization, the hierarchy usually consists of a singular/group of power at the top with subsequent levels of power beneath them. This is the dominant mode of organization among large organizations; most corporations, governments, criminal enterprises, and organized religions are hierarchical organizations with different levels of management, power or authority.
Renewable energy in developing countriesRenewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019.

Emploi de gré à gréEn droit du travail américain, le régime juridique de l'emploi de gré à gré (anglais : employment at will ou at-will employment) donne la possibilité à un employeur de licencier un employé pour quelque raison que ce soit, c'est-à-dire sans avoir à établir un juste motif pour le licenciement, et ce, sans avertissement tant que le motif n'est pas illégal (par exemple, un congédiement en raison de la race, de la religion ou de l'orientation sexuelle de l'employé).
Termination of employmentTermination of employment or separation of employment is an employee's departure from a job and the end of an employee's duration with an employer. Termination may be voluntary on the employee's part, or it may be at the hands of the employer, often in the form of dismissal (firing) or a layoff. Dismissal or firing is usually thought to be the employee's fault, whereas a layoff is generally done for business reasons (for instance, a business slowdown or an economic downturn) outside the employee's performance.
