Is this BCBA being unethical or am I being sensitive?

Hi. I never post on reddit but no one in my life knows ABA like I do besides my coworkers and I don’t want to talk to them and create conflicts but this is heavy on my noggin and heart. I really need to know if I am being too sensitive or if this is actually unethical.

I’ve been an RBT for almost 2 years and am in school to become a BCBA (third year of undergrad). I love love love my job and for sure have found my calling. Recently though, I’ve noticed some interventions/strategies from my supervising BCBA that I don’t feel super comfortable doing.

For example, one of our kids has an AAC and sometimes presses buttons of items that are unavailable such as the playground (it’s too cold to go on right now) multiple times. Typically the client does this, I will remind him it’s unavailable, and provide other choices that are. She interrupted me and said “you can just hide that button”. She also hides most of his buttons if they’re unavailable and I constantly am unhiding them when I am in session. It’s an AAC device not a choice board! The client doesn’t even typically engage in behaviors when denied access anyway so it’s not like it’s trying to be an antecedent intervention. (This I KNOW i’m not being dramatic about because what if I duct taped ur mouth because you kept repeating a word?)

Another thing, she talks to the kids in a very stern voice. I’m not sure how to describe it besides her sounding angry or annoyed. For example, one of our kids has gained a lot of interest in his peers and often asks where they are repetitively. After she’s answered a few times she then goes to saying “I don’t know where are they?” in a sarcastic, stern tone. Or when she is engaging in interventions it isn’t in a calm neutral tone, it’s very stern. She also encourages another RBT to do this while working with kids and it makes one of them engage in a higher frequency of negative vocalizations and aggression. I’ve worked with him for so long and he does great but when someone talks to him like that it makes him so upset (rightfully so). You can actually see an increase in his interfering behaviors when she is working with him.

Now the thing that has been bothering me the most recently is a new intervention plan she is having us implement. It’s a calm down corner. Very time out coded and the child finds it extremely aversive. She was supervising me today and the child began engaging in aggressive behaviors as well as negative vocalizations and flopping when denied access to an item. She (aggressively) scooped the child and took him to the corner while restraining him to the chair there. While we’re there we are supposed to give him options of different regulation techniques (deep breathing etc) which I don’t mind i think emotional regulation is an important strategy, but she told me not to provide any reinforcement and not to give him a hug. He was screaming and crying and was NOT calming down (probably because he was being restrained into the chair) and she wouldn’t let him up until he stopped. She also told me not to acknowledge his feelings like “you’re blank because of blank this is what we can do to calm down” because she said it was too reinforcing. I understand not wanting him to pair engaging in those behaviors to a highly reinforcing activity but i don’t know watching it made me want to be sick and it felt cruel.

There’s a few other things she does that I’m just not sure aligns with our ethics codes and I’m not sure what to do. She’s highly respected in our clinic and she’s my main BCBA that I meet with monthly. We have 4 other BCBAs and a clinic director, but I am scared to step on toes and lose my job. I love all of the BCBAs and clients and other RBTs but I just am unsure about this BCBAs conformance to the ethic codes.
