I’ve been giving this a great deal of thought. Let me start with series of questions: If you were in a wheelchair would it undermine your authority and lead to blame? If you were epileptic and had a seizure at work would it undermine you? Would your staff blame you for it happening? Would they doubt your leadership because of it? Do you wear glasses to correct your eye sight? If you do does it undermine your leadership?
Do you see where I’m going with this?
You have a disease/chronic condition that you manage on a daily basis. In essence, it is you. Unlike people in wheelchairs or wearing glasses, your issue is hidden. This does not make it less of an issue or less important to your daily life but it does give you the option to not discuss it. The thing is, sometimes not discussing something makes a situation worse, not better.
I’m not advocating wearing a bright yellow t-shirt that says “I Have Daily Pain” on it in bright orange. But I’m not advocating hiding something that impacts you or your work.
I have neurologically complicated migraines, ATN, and lymph edema in my left arm. None of these things can be seen. All of these things impact me on a daily basis and impact what I am able to do and how I am able to do it. With the lymph edema I have limited use of my left arm, which you would never notice until you asked me to lift something. At first I would, often flaring the lymph edema by lifting something I shouldn’t have. Now, I’m very straight forward about the fact I can’t lift with my left arm - I mean I can but it will cause the lymph edema to flare up for days after so for my own well being I can’t. So I decline to lift things and ask for help for even the smallest item to move that requires two hands. People have always been very understanding. I didn’t make some large general announcement, but when it came up I explained.
I’ve handled migraines and ATN about the same way. Sometimes migraines make me very angry, I call it “free floating rage” because there’s no reason for me to be so angry at every little thing, but it does happen. When it does I have warned the people I work with directly that I’m having rage issues because of a migraine and to leave me alone, that I don’t mean to be a bitch on wheels, please forgive me, and please go away for now. It’s worked for me the majority of my career.
I actually think being upfront with people I work with every day on an as-needed basis has helped me, not hurt me. My colleagues know I’m honest, they know I have issues, and they know I will not let those issues impact my work or theirs.
I do want to stress I didn’t make some general sweeping announcement about me and my life, I simply informed people as-needed and let it go from there. The gossip took care of the rest for me, information about me gradually spread around and it was no big deal. In fact, I’ve had people approach me with questions about migraine, people have literally come up to me and said “I heard you have migraines, I was wondering…”
When people know there are things going on with you they actually do understand and will make allowances (within reason) for things like being late on occasion. Your biggest challenge is you must never been seen to use your issue as an excuse to do poorly.
