Final answer:
Job descriptions are crucial for effective communication in the workplace, recruitment, and human resources management. The rise of automation and Internet connectivity has influenced how job descriptions are formulated, shared, and utilized in today's job market.
Step-by-step explanation:
Job descriptions are indeed necessary in today's workplace. They serve as a foundational element for various aspects of human resources and organizational management. Significant reasons for the continuation of job descriptions include clear communication of job expectations, aiding in the recruitment process, and facilitating the development of training programs and performance appraisals.
With the impact of automation and technology in the workplace, job descriptions must evolve to reflect these changes. Automation has allowed for routine and repetitive tasks to be handled more efficiently, leading to a shift in the types of jobs available and the skills required for them. As set out by Davis and Moore, jobs that require a high degree of skill often determine a job's importance in society, and a clear job description helps to identify and communicate these skill requirements.
Furthermore, the role of the Internet and social networking sites such as LinkedIn has dramatically changed how job seekers and employers connect. Job descriptions posted online help to attract candidates with the right qualifications and skills, regardless of location, thereby broadening the potential talent pool and changing the way jobs are advertised and performed.
