You see lots of us are in full time jobs, and I guarantee that it is not the experience of our employers that we are a liability. far from it! People with KC tend to be a highly motivated bunch, and the business of finding ways round our problem makes us adaptable and focused.
These are positive benefits that we bring to the workforce.
Your woman at the jobcentre ought to be reminded of her duties under the DDA and you are entitled to ask, as John has said, for a referral to their Access to Work Team. Their intervention may make all the difference in any contact with potential employers.
It does occur to me that the woman whom you have met so far may be talking to her first ever jobseeker with KC, in which case she has spoken in ignorance. It is our job (yours, mine, John Smith's, Anne's, Jayuk's et al ...) to attack prejudice and overcome it!
Now that gets you motivated in the morning
Every good wish
Andrew
