Octavia Knows That,as a Manager,it's Not Always Right to Treat

Octavia knows that,as a manager,it's not always right to treat everyone on your team in the same way.For instance,she has a great relationship with Raoul and Sally.She trusts them,they work hard,and they've never let her down.To Octavia,these team members are invaluable,and she makes an extra effort to send challenging projects their way.
She doesn't think of Gannon,Lilly,and Kathleen in the same way.They don't have far-reaching career goals,they're less competent,and Octavia simply doesn't trust them to the same extent.These team members get everyday responsibilities,and are not considered for promotions or challenging assignments.
Why doesn't Octavia trust certain team members? Does she let that distrust,or the belief that they're unreliable,influence how she relates to them? Does she,even subconsciously,withhold opportunities that might help them grow and succeed? This is an example of the leader-member exchange model of leadership.Describe the details of the LMX model,including the relationships and implications.
