Final answer:
Denise should perform job evaluations to assess the worth of jobs in her gym in comparison to each other. Other methods like taking wage and salary surveys, examining job descriptions, and analyzing job specifications provide valuable information but do not determine internal job value.
Step-by-step explanation:
If Denise wants to determine how much the jobs in her gym are worth in comparison to one another, she should perform job evaluations. Job evaluations are a systematic way of determining the value/worth of a job about other jobs within an organization. This process often considers factors such as skill, effort, responsibility, and working conditions. Assessing these aspects provides a foundation for forming a pay structure, ensuring fairness, and establishing job hierarchies.
On the other hand, taking a wage and salary survey might be useful for understanding how the gym's pay compares with the external labour market, but it does not assess the internal job value within the organization. Examining job descriptions and analyzing job specifications are helpful steps for understanding what each job entails and the skills required, but these do not deliver a comparative value of different jobs within the gym.
Observation, surveys, and interviews are practices often used in job analysis. Job analysis is essential as it lays the groundwork for job evaluations by collecting information about jobs, including tasks, skills, and responsibilities. Denise could also engage in the demand and supply analysis of labour markets to understand the competitive salary rates in the market, thus aiding her in benchmarking against other organizations. This will support Denise in coming up with an equitable and competitive compensation strategy that is both fair and attractive to current and prospective employees.
