Workplace adjustments

Hi all! 

Just wanted to check something before making any workplace adjustments. I think I do know the answer but I’m struggling to find confirmation on this. Am I right in saying that any disclosure or workplace adjustments you need in a current workplace can’t be disclosed in a reference or anything in the future? I need some adjustments where I am currently working and I don’t care too much about any possible negative impacts because I know the workplace and am also not planning on a long career here. In the future I am hoping to find a job more suitable so might not want to disclose I am autistic especially not prior to getting a job through a reference from an old workplace. Just checking if I’m right on this!

Thanks!
