A Short Conclusion Related To Employment Law Discipline

Can anybody help me with employment law? ?
I have had alot of time off sick for which I have need hospital treatment on several occasions. Now my employer has called a discipline hearing. My union rep, said they had recently lost several disciplinary hearing for sickness. So i decided to hand in my notice, has my rep said the hearing would be cancelled if I did, and I thought it would look beter if I left, rather than be dismissed. But now my employer say they are still going ahead with the hearing. Does anybody know if I can still be dismissed after I have handed in my notice? Or can anyone give me any advice?
this hearing has more to do with the union then it does about you.
excessive absenteeism is grounds for termination with cause with or without union representation. the reasons for absenteeism are unimportant unless they fall under FMLA. as your rep noted the union has lost numerous cases involving absenteeism and the company must stick to their policy and equally enforce it with everyone. there really aren't any options for the employer but to go ahead with this. as far as how it effects you it could help in your ability to qualify for unemployment insurance, assuming you are able to work and are actively seeking employment.
