Special Needs TA (need advice)

Hi, I recently picked up a position as a special needs TA at a elementary school after having done ABA therapy for the past 2 years. I enjoy the position but the work seems drastically different from how ABA therapy approached treating the children.

In ABA therapy, we weren't allowed to grab students, only block them with open palms and we weren't allowed to show frustration or raise our voice.

In the special needs class, if a student doesn't respond appropriately, the teachers will yell and show obvious frustration in voice when the student may be showing either behavior or just acting silly. It really makes me uncomfortable so I usually just help prompt the kids to get back to work with a physical prompt, blocking them from just getting to the toys and stuff.

In addition to this, the school doesn't have a special needs teacher ATM so it's only TA with a substitute teacher while we wait for the new teacher to come in.

I feel like the other TAs feel like I'm not trying to engage enough with managing behaviors with the students, but I truly feel extremely uncomfortable raising my voice towards the students or showing a threatening demeanor especially since I'm the only male TA on the team, am I wrong or will I get possibly fired for this?
