In New York State of Year2020, COVID-19 pandemic surged in NY along with major cities worldwide. NYS endured mass unemployment encountering an overload to their Unemployment Insurance, exascerbating the outdated flawwed system, crippling their phonelines, with incessant call-ins of claimants' issues all day; every day; every week, hoping to reach a human voice on the other end, only to consistently and repeatedly disconnected due to unavailable representatives. Yet, many persisted madly dialing robotically 888-209-8124.

The definition of insanity, is doing the same thing over and over again everyday thinking this time it will change. The first time someone told me that I didn't believe them so I ignored them...but after a while everywhere I looked was the same people doing the same exact thing every single day that things are going to change and when it doesn't they think, no maybe things will change when they never will. That is the definition of insanity.
