I have had this condition for several years and certified intermittent FMLA each year. I take individual and sometimes continuous days off of my very heavy physically demanding job. I am union. I take off work when I cannot complete my duties. When I go to work I am a little slower than I used to be, I would say what used to take me 9 hours, might take me 10 but only when a little sore. My company is attacking me daily saying when I am gone the people filling in are faster and more productive. I have been there over 20 years and was recently confronted like this in front of my co-workers and it was highly embarrassing. I was told if I can't do the job to their standards I should look elsewhere for work. I am in shock and destroyed after all I have sacrificed for this company.
