I need an explanation for this Management question to help me study.

Society has evolved over the last century causing organizations to change with the times.

This evolution has, in turn, required workers to “re-tool” to be a productive and indispensable member of the workforce.

• Using this lead-in as the context, describe the workforce shifts in types of jobs during the past hundred years. Also, answer the over-arching question, “What implications have these workforce shifts created for today’s HR manager?”

The requirements below must be met for your paper to be accepted and graded:

• Write between 750 – 1,250 words (approximately 3 – 5 pages) using Microsoft Word in APA style, see example below.
