My Comment:

Excellent edit! You followed the steps outlined by the text:

To fix sentences with long, abstract subjects, revise in three steps:

1) Identify the main character in the sentence

2) Find its key action, and if it is buried in an abstract noun, make it a verb

3) Make the main character the subject of that new verb.

In this case-

1) The main character is Human Resource Managers.

2) Consider is the key action.

3) I am glad you placed it directly after the main character in sentence.

Listing the subject only once in the revised sentence improved clarity.
