When I was six years old I was diagnosed with KTS syndrome. It is rare genetic disease and my left leg is affected by it.
Since May 2015, I'm working in a warehouse. I didn't inform my employeer about the disability I have. I was afraid that I'll get discriminated, and my disability allowed me to work back then (no pain, no problem).
Now after 3 years my leg is getting worse, I feel big pain when I'm walking for longer than 30 min, I can't carry heavy objects anymore without feeling a pain. And my job is all about constantly walking and lifting heavy boxes, which makes my everyday work a pain. I'm working part time. I know that in my work there are positions that are a little bit more suitable for me, (Like 50% sitting, 50% walking), or there is position when you pack things sitting on a chair.
Can I inform my employer that I got a disability and it got worse without fear of beeing sacked?
Is he still obligated to help me with my employment even if I havn't inform about my disability when I was hired? (Like I said, It didn't give me any symptoms before, and also I was scared of discrimination)
