Promotion is what many employees expect from their jobs. Climbing up the career ladder is especially interesting to junior professionals who cannot apply for top positions because of the lack of experience. Some knowledge comes with the experience only, and there is no way to gain it at college or university. Years of practical experience in the field make employees particularly valuable to the company and create opportunities for their further promotion. Perhaps, companies shall stick to creating hierarchies basing on the seniority of their employees in the first place.
A college degree combined with some basic skills can be an important condition for companies to hire a junior specialist. A required education and some previous experience make it possible to hire candidates. But companies need something bigger to promote their current employees. Seniority is the first essential factor. The longer employees work in business, the more loyalty and understanding they develop. But being loyal and ambitious is not enough either. Sometimes employees gain promotion with the extraordinary performance. It indicates that they are capable of taking a greater responsibility and completing more complex tasks.
And last, employees are eligible for promotion when they gain more new skills valuable to their company. Getting some extra training or continuing education, people declare that they do not intend to keep working at the current position until they retire. And that is a strong marker of the looming promotion. After all, employers cannot teach their staff all the skills they need, and getting more education outside the business is crucial.
