Does your job title matter?
Once upon a time the workplace was simple. There were two roles: workers and a boss. Now, especially in larger organizations, there are chiefs of everything. And in almost every government department there are not just supervisors, but heads, managers and directors, and director generals.
Major Canadian companies are no different. Air Canada, for example has a CEO and CFO, but they also have an executive vice-president commercial, a senior vice-president and CCO (chief commercial officer), an executive vice-president and CIO (chief information officer). In addition they have a series of other vice-presidents, senior and otherwise, that range from VP Airports to Revenue Management to Global Sales.
