My disability is not obvious or visible. Up until now I have only told close family.
Recently, I have been considering job hunting to try to improve my salary. I currently make around 50k USD. I'm based in Japan so this salary is not terribly low but also not that high.
In Japan, companies have a requirement to hire a certain percentage of disabled people. Looking at the Google recruitment site I can see they have a program (gReach) specifically for registered disabled people.
Is it a good idea to disclose my disability during the application process? On one hand I feel like it might encourage companies to interview/hire me to fill their quota. On the other hand I worry that companies may be prejudiced against disabled people and use it to disqualify my application.
Once you are hired, disclose it on the very first day, with a letter from a doctor that details what accommodations are required for you to do the job. Unless you don't need accommodations, in which case do not disclose it.
Disclose it to companies who have programs to support people with disabilities
Don't disclose it to companies who don't have a support program
Other than that, my personal policy is to not disclose unless I need some kind of accommodation (which I generally don't). I think the risks of having it consciously or subconsciously counted against me outweigh the potential benefits of being favored by a quota.
I have MS which causes urinary incontinence and my mobility is impaired (unable to stand for too long, cannot walk for longer than 100-200 meters at a time and so on).
Disability hiring quotas are most effective for those with mobility impairments.
In the U.S., medical information disclosed to insurers has strong privacy protection under HIPAA. The HR department must keep information about a treated disability confidential, even if you haven't discussed it with coworkers.
Your improved condition after diagnosis and treatment is a powerful affirmation of your character and determination, qualities that would benefit a new team.
