I would keep it to yourself until you get a sense of the reception you would get from your coworkers or manager. Let them get to know you first. Also, if you find you will need some time off work, including a day here or there, complete FMLA paperwork so your job is protected. Those days off can't count against you then.

Check out the Americans with Disabilities act. I'm pretty sure if you inform your employer, he will be required to make reasonable accommodations. Do some research on the internet to make sure fibro is one of the covered medical conditions. If you fit in, he will not be able to fire you due to your disability. Double check my research before you whip it out though, I don't want you do have any detrimental effects if you are not covered or the company does not have the right amount of employees to fall under the ADA. Good luck!

Thank you for all your thoughts! I told my employer and co workers, but I said in passing and assured them my condition should not interfere with work. My boss told me if I run into a problem, I can work from home!

The problem with not telling your employer is that if you are asked to do something that you know you cant or shouldn't do because of the fibro, you would then have to inform your employer of your health situation. I feel this may show possible honesty problems. Withholding information from an employer particularly when it comes to health I feel is not a good idea. I do know that the ADA says that an employer must make 'reasonable accommodation' for those with disabilities and that applies in all States....these are only my opinions! Merry Christmas everyone and keep well.

I would wait to say anything. Get secure in the job first and show them that you're a valuable employee first. Unfortunately, there are people that don't think fibro is a real illness and you never know who might react that way. And like the other poster said, if you find you might have to miss work due to the fibro, get the fmla paperwork in so your job is secure. Good luck :)
