You could just wait and see how things go. It might make sense to just call in sick those days, at least at first, and avoid the whole conversation until you have a better sense of how much time off you really need. An employer is going to be less unhappy if it's just 2 hours at the end of the day as opposed to an entire day or more.
If you end up needing to take a whole day every 6 weeks you probably are going to have to discuss the issue with your immediate supervisor so you don't get accused of abusing their policies about
time off.
In that case I strongly suggest you carefully review the information in this document that discusses the difference between FMLA and ADA and what information an employer can ask for, what constitutes a disability under ADA and a serious health condition under FMLA and lots of other good stuff. You will see that the employer is NOT supposed to collect details of the health condition under FMLA, as happened to the other person who posted about
this.
www.eeoc.gov/policy/docs/fmlaada.htmlAs you can see, normally you should not have to disclose anything more than that you require time off for medical care assuming you are going to use sick leave or vacation for your treatments. Just like you would for any other health condition you'd call in sick for but you are doing them the courtesy of letting them know you will be able to give at least 2 weeks advance notice of an expected absence from work.
When I had to be gone for regular medical appoints I had already have given some thought to ways that I could share my work load with a co-worker on those days. I offered to work a bit longer over several days to make up for the time off. But this was not legally allowed in my state without incurring overtime costs.
If you do this, you can offer your immediate supervisor this info (if you think wise) at the same time you are letting them know you will be taking a day off now and then for medical care. This may help ease your supervisor's anxiety considerably.
If they fuss about
giving you time off then you may want to considering telling them you have a disability (no specifics should be required) that requires this reasonable accommodation and are they saying they will not allow you this reasonable accommodation? Preferably put this in writing and request a written reply...You are unlikely to get a written reply saying NO since this would be illegal.
They may want a doctor's verification in which case you can ask your primary care doctor (not GI) to write you a vague letter stating that you have a chronic disability that requires regular treatment. The doc should state that, because of your disability, you need a reasonable accommodation of up to 1 day off every 6 weeks.
Based on my experience, this should be more than sufficient information. If you have a Disability office at your employer you could approach them with this info and request for assistance. These offices are usually bound by privacy laws that prevent them from sharing health info beyond the certification to your immediate boss that you require accommodation. I would think of any other accommodations you need and have them included at the same time. No details unless it is necessary to provide the accommodation.
An example of this would be that you need a special chair to reduce your belly pain and you have to help figure out what chair to order.
Another common accommodation that may have to be requested depending on your employment situation is unlimited, untimed and self-determined bathroom visits assuming you have D. The Disability office doesn't have to tell them why you need bathroom visits, just that this is an accommodation that must be provided.
