Hi Jim,

Its nice to meet you! I think you need to disclose to the employer that you have MG. I think AliceMD put it really well, thank you Alice and welcome to the forum.

You need to disclose it as it would then give you protection under disability laws ( Im assuming here that you have something similar to the UK's Disability Discrimination Act) and also it would enable you to work with an employer to make adjustments for you. Without them knowing you would be expected to perform the role the same as anyone else. When it could be you need extra breaks or a desk closest to the bathroom etc etc.

I hope this helps

Love
Rach
