Once again, FMLA is medical leave ONLY and does not entitle you to any work modifications, light duty, or changes in duty. If you need to be off work entirely, that's FMLA.
If you have a long term or permanent disability and need modifications or accommodations, that's the ADA. However, the ADA does NOT cover short term disabilities. For this purpose, short term would include pretty much anything less than six months.
Everything else is a matter between you and your employer and is not a legal issue.
Because it is not a legal issue, you are free to see whatever doctors you want and as often as you want. Since you've already turned in your FMLA forms and neither the ADA nor workers comp applies, the law doesn't care what doctors you see.
ok good then I will proceed diligently to have all restrictions lifted so I can return to full hours, they are interpreting these as self imposed, because I was being too honest with them about how the doctor came up with them, I have a big mouth apparently and I need to work on that, honesty is not the best policy in this case. I just hope they dont have something else up their sleeve after I give them the new note from the new doc or chiro
