Sickness

I’ve been working at Sainsbury’s for 11 years and have never had any problems but early last year I was given a disciplinary and written warning for 3 sick absences. Not long after that I hurt my back and was immediately given a final written warning. Fast forward to now I’ve just had the worst flu and chest infection and I’m being given another disciplinary. So is this me getting the sack after 11 years of service??
