I am disabled now and had to leave my place if employment in Sept 2015. They terminated me March 2016. I was there for almost 19yrs. I live in PA and when I worked there in 2014 I had a boss who one day took me in his office and said very rudely.....DO YOU REALIZE EVERYTIME I TALK TO YOU, YOUR MOUTH TWITCHES. I said excuse me? HE SAID IT AGAIN IN THIS MEAN HORRIBLE HATEFUL TONE. I was his right hand girl and ran his call center for 5yrs before he decided one day to demote me for no reason. He is still with the company and keeps moving up the ladder. Well, my face tick has been going on for about 9yrs and NO ONE TOLD ME. NOT EVEN MY KIDS. This still haunts me to this day that he pulled me in and reprimanded me for this. Do I still have time to sue him for HARRASSMENT. Every month my doctor makes notes of facial ticks. Now I am 50 on social security disability. My company denied my Long term disability which should have been paid until I was 65. Then the day I left they told 8 of my girlfriends to NEVER SPEAK TO ME AGAIN OR THEY WOULD LOOSE THEIR JOBS. I lost 8 of the best friends in the world because of this company. I had to go to therapy for 3yrs to deal with all of this. My pain in my body, what he did to me and loosing all my friends. Plus NEVER BEING ABLE TO WORK AGAIN. Do I still have time to file a HARRASSMENT CASE AGAINST MY FORMER BOSS AND THE COMPANY? Thank you
