"And it's true, I don't know if maybe we were victims of bullying, and it's a very victim thing to do to blame yourself, which is what people were saying, but … the only person who was honest about it was Naya.
"It was something that was very hush-hush on set, and now you see all these things coming out with these bigger names who were very disrespectful and mistreated a lot of people.
"We absolutely could have stepped up and gone to the Fox execs and said how we felt about the situation, but no one did.
"I think many people were very scared, and I know, genuinely, I felt like it wasn't my place, and I don't know why because I was a cast member."
And Morris speculated that some of Michele's behaviour could have been connected to her mourning her co-star and then-boyfriend Cory Monteith, who died in July 2013 after an overdose.
She said: "We all got close with Lea at different points, and then we all weren't as close with her.
"So there's that human element to understanding who this person is, growing with that person, seeing her try to become better and taking care of herself after Cory's past. It was just the elephant in the room."
Morris previously claimed Michele had been "unpleasant to work with" on Glee.
In a statement shared after her former co-star apologised to Ware, she said: "Let me be very clear, Hate is a disease in America that we are trying to cure, so I would never wish for hate to be spread to anyone else. With that said, was she unpleasant to work with? Very much so; for Lea to treat others with the disrespect that she did for as long as she did, I believe she SHOULD be called out.
"And yet, it's also on us because to allow it to go on for so long without speaking out is something else we're learning along with the rest of society.
"But, at the current moment its implied that she is a racist and although I cannot comment on her beliefs, I think we're assuming, and you know what happens when we all assume... (sic)."
