AIO for not wanting to pour bleach and chlorine down the same drain?

Hey! Short and sweet one, I work in a facility where we spray down our floors with a diluted chlorine solution each week, and then this is wet vac'd up and the dirty chlorine solution dumped down a sink. Both sinks I have available to dispose of this in have diluted bleach dumped in them regularly. Our washers drain into sink #1, and we use bleach in those. Sink #2 we soak various items in bleach solutions to disinfect and then those get dumped. I always rinse the FUCK out of the sink I use before I dump the chlorine because wtf.

I brought up to my manager today that this made me incredibly uncomfortable (ya know mustard gas and shit) and she was incredulous. Laughed me off, couldn't believe I had an issue with it, surely this isn't good for the pipes or the system or us? I'm newer here--only done this twice--and I guess they've been doing this for months so I'm like maybe I am just paranoid? Am I overreacting about the possibility of getting gassed as fuck the next time I deep clean?
