Bob,
Obviously your assumptions above can not be correct. The catalyst for FMLA was for folks who were non-union and were not permitted to take time off (without pay) to care for a loved one without jeopardizing their job or for their own serious injury or illness. That is how and why legislation came about. You must be living a shallow existence if you never ran across someone needing such a benefit.
Unionized received this as a "fall-out" of the law. And flight crews were not included because of the yearly hour restraints. We as USA AFA negotiated language in 2000 called PCL Personal Care Leave. This leave falls under the umbrella of FMLA and there fore we qualify. However, mangment applies the FMLA to every single leave, whether its OIJ, Medical, over 14 days sick, personal, maternity...they want you to hurry up and use up the benefit, so if in the course of the month you have another type of illness, you have no "job protection". They CAN terminate you for your illness at that point depending on the circumstances.
Folks should never sign the FMLA paper work UNLESS you are specifically by wording requesting and FMLA or PCL. Medical leave documentation IS DIFFERENTPAPERWORK. Mangement will "sneak" the FMLA paper work along iwith it just to get your signature on them so you can't deny you idn't request it . Throw these paper in the trash when you get them. You only need to fill out medical leave of absence documentation along with your physician. Mangement will try to convince you to fill out FMLA also...DON'T SIGN THEM.
If at any time an employee feels they are being discriminated against for age or disibility for a chronic illness...Visit an attorney or local gov. office and fill out and file EEOC and ADA claim.
