I have been looking for work I am unemployed since june2018 back is shot employers can see that right away can I get an exstention on my unemployment.

Worker's comp is for people who were injured on the job. Unemployment insurance is for people who were fired. Social Security Disability Insurance, getting your Social Security retirement benefits early, is for disabled people who have paid into the system for at least 10 years and apply within 5 years of the time they last worked. Supplemental Security Insurance is for disabled people who have not paid or not paid in enough years or not applied within 5 years of the time they last worked. From your description, it appears that you are too late to apply for worker's comp or unemployment insurance but may qualify for SSDI.  To qualify, you must be unable to do any job, not just your regular job.  You can apply online at www.ssa.gov.  Most people are denied and must ask for reconsideration (ask for an informal conference so that you can explain things).  Some must ask for redetermination, which involves a review by doctors not employed by Social Security.  A few must appeal further, to an Administrative Law Judge.  You only need an attorney for this last step.  Promptness, politeness and persistance are key.
