Is it morally/legally right for an employee to disclose their condition/illness to their boss?

Unless a person’s condition has an adverse effect on them being able to perform their job safely, they have no obligation to disclose any medical condition to their employer. That is confidential patient information.

If you’re a truck driver and are prone to seizures, then you might have to disclose it.
If you’re working in an office and are suffering from a psychological condition, then no, there is no need to disclose that.

It’s a medical condition that can be disclosed at the employee’s discretion. Unless it’s affecting job performance, there would be no legal reason to inform the employer.

If there is a clear possibility that the person’s job will be affected, then it might be better to disclose once problems arise.

Here’s where there’s a legal “obligation” – if one wants potential accommodation, the employer has to know (or reasonably should have known) that there is a “disability.” If they don’t, then they can fire an employee with a disability without recourse.

Yes, it’s morally (and potentially legally) right if it’s a matter of safety (yours or others). Your boss may need to know if you have a condition that requires special or prompt treatment so you get the right sort of help in an emergency.

Is it morally or legally required? No. Big difference.

You should only do it if it affects your performance, or your likelihood of missing work.

When I was first put on depression/anxiety meds, I told my boss. I thought it was the best thing to do because I knew there would be an adjustment period where I would feel a little out of sorts. Disclosing that info also helped out when I was adjusting to different dosages and developed migraines, which led to my missing a few shifts, and when I began to have panic attacks during which I would have to leave the sales floor.

Depending on the severity of the bipolar disorder and the patient’s individual coping skills (i.e. if it’ll lead to missed shifts or potential breakdowns during the day like I experienced), it’s probably a good idea to tell an employer.

I agree with those above, if its something that is going to be showing itself at work you should tell your employer before hand. But I think if its something that will never arise or become an issue of any sorts at work than I dont really see a need for disclosing it.

what must be morally disclosed?
