A local oil and gas company in Houston hires the following categories of employees: 1. Petroleum Engineers at all levels (entry level, senior level, middle-management level, etc.). 2. Clerical employees (entry level only). 3. Senior management staff (both internal and external searches are done). The company employs about 3,000 employees in the Houston area. The company is interested in revising its compensation package to be externally competitive. They want to conduct their own market survey of wages and benefits paid by the competitors. Help them identify the relevant labor market, competitors, and the key areas they should focus on in designing the survey. Note that I do not expect an actual survey but the areas they should cover in terms of whom to survey, what to survey, and where to survey.
