I NEED TO KNOW IF I HAVE A CASE

I WORKED FOR THE CIYY FOR 26 1/2 YEARS. IN 2005 I WAS TOLD I WOULD BE PLACED AT 311 CALL CENTER - EITHER TAKE THIS POSITION OR BE WITHOUT A JOB. THIS JOB CAUSED A LOT OF STRESS TO THE POINT OF MY DR PLACING ME ON MEDICATION (WAS ALREADY ON H/B AND DIABETIC MEDICATION) INFORMED MANAGER OF MEDICATIONS AND ALSO DR FILLED OUT FMLA PAPERS - THE CITY HAS A SIX MINUTE GRACE PERIOD BUT AT 311 THAT STATE THAT WE HAVE A SIX MINUTE GRACE PERIOD BUT ARE LATE AFTER 1 MINUTE. HOW CAN YOU HAVE A 6 MINUTE GRACE PERIOD BUT STILL LATE AFTER 1 MINUTE? I WAS LATE 5 TIMES IN A 30 DAY PERIOD WHICH TOTALED 11 MINUTES. DURING THIS TIME MY BLOOD PRESSURE/DIABETES WAS OUT OF CONTROL AND MY STRESS MEDICATION WAS INCREASED FROM 50 MG TO 100 MG. I THOUGHT I WAS LOOSING IT. I WOULD BE TALKING IN MY NORMAL VOICE I THOUGHT BUT WOULD GET CALLED IN STATING THAT I WAS RUDE. IF I WAS SUCH AN AWFUL EMPLOYEE I DON'T THINK I WOULD HAVE BEEN EMPLOYED FOR 26 1/2 YEARS
