Russell received a 40-game suspension for violating the joint domestic violence policy and has 28 games left to serve.
"We're all on the same page with it," Hendricks said on Inside the Clubhouse on Saturday. "We're all on board. We love Addison. We love Melisa too. Everything that happened is unfortunate. We're just behind him. He's our teammate, and we're backing him. We want him to be the best person he can be, whatever that process is going to take. We're focused on on the field and what we have to take care of business-wise, but obviously just who he is as a person and the developments that he's going to make, we're here for him. Anything he needs, anything really anyone needs in this situation, we're just trying to be as supportive as we can."
Russell can make up to $600,000 in incentives if he's on the active roster for 150 days, which is close to the amount he will forfeit for missing the first month-plus of the season with his suspension.
Hendricks praised how president of baseball operations Theo Epstein has handled Russell's troubles. Epstein has emphasized the Cubs want to help be a positive force in the life of Russell, who turns 25 on Jan. 23.
"That's where Theo steps in," Hendricks said. "He's always looking for something, anything that can help. There are a lot of meetings that we have in spring training that are new, that didn't happen years ago, like domestic violence meetings. We bring people into the complex to talk to the group, just education in general. From Theo and the front office's side, they're doing everything they can, and I know Addison is on board and he wants to become the best person he can be. It's just both sides balancing it out and seeing what the best outcome is going to be."
