Research is the heart of what we do. Every employee, without exception, has research responsibilities. In fact, over 80% of our man-hours are devoted to research.
Every country is assigned to an analyst, who "owns" responsibility for ensuring the data we provide for that country is accurate, complete, and current. It is the analyst's job to understand the dynamics of each center's holidays and to remain fully informed at all times about every information channel needed to quickly identify any changes.
Each center has its own dynamics. In some, the holidays are determined centrally. In others, they may reflect the input of half-a-dozen different entities, such as government departments, religious authorities, labor unions, etc. Whatever the facts, it's the analyst's responsibility to understand them and know how they impact the holidays.
