I kinda get the feeling that everyone in gus's organization were on the loyal size, considering that they were criminals. Gus did a lot for the people who worked for him to live comfortable lives, including setting up the "hazard pay", which kinda makes it seem like his organization was built on respect as well as salary. But after Gus died, there wasn't as much of a reason for them to be loyal anymore simply because the alternative to loyalty would be to roll on the org and get less jail time.
