This is a dilemma of my own in some respects also. I began this job I have now in the public sector two years ago - before I was diagnosed - and now I am, I have not broached the subject with my line manager or any of the staff.
My doctor has told me that I do not need to mention it to them, since it is a developmental disorder and NOT a mental disorder. In some instances, I feel it would be helpful if my colleagues knew but like you, I'm a little edgy about actually telling them.
The bottom line is, I think, if you feel you can cope with the job and don't think your AS will matter, there's no need for them to know. Maybe, when youve done the job for some time and proven your worth at it, that's the time to come clean. That's sort of how I'm thinking anyhow - although I haven't actually bitten the bullet yet.
