From my (limited) knowledge of the industry, yes.
If you are wanting to jump into the RHS with little to no commercial experience, airlines will ask for a MCC and JOC.
The analysis that most incidents are caused by pilot error, of which the majority could have been prevented, has led the way to pushing good CRM skills amongst crews. The MCC helps to establish this, and gets you into a mindset of how to fly safely in a multi crew environment.
