synergies between Industrial Relations (IR) and Human Resource Management (HRM)

I need support with this Management question so I can learn better.

Drawing on the three readings attached (Frege 2008; Kaufman 2008; Lepore 2009), describe these synergies and their significance today. For full marks, be sure to:

a) Briefly describe how the fields of HR and IR emerged

b) Briefly describe how our understanding of IR has changed over time

c) Briefly discuss the relationship between HR and IR today

The assignment should be 3 pages long, double spaced.
