Walk through a patch of ivy shoulder high some time and tell me you won't get the heebyjeebies!
Ok! I don't. No heebyjeebies for me.
I routinely pull the stuff up barehanded. Once cut/ripped out, rake into a pile and throw onto a truck. Strim trim: juice splatters everywhere. No protection needed, as I am not allergic to it at all.
I have given it to my wife several times, however. You can imagine how well that went over. So far, she refuses to take the Rhus Tox, so no relief in sight. I am safe so long as I bleach it away. This is a fix that probably won't work for some people.
I have a lot of experience with employees and problems, though. Some people are so allergic they must go to the hospital if they just brush up against it. In my experience, some people get worse reactions the more they are exposed to it, but most have diminished responses as they are repeatedly exposed. Several of my guys have gotten to the point that they came down with a mildly irritating set of bumps once per year. after that, they were good for the rest of the year.
When Enrique started working for me, he needed steroid shots to reduce the severity of the blisters and rashes. After a couple of years, he was down to just getting a few itchy bumps. Many exposures, and a little Rhus Tox.
By the way: poison ivy leaves are nearly indistinguishable from Box Elder. The critical difference is that leaves are alternate on PI, paired on the Box Elder, which is a variety of maple tree. Don't count on PI being a vine, or having toothed or smooth leaf margins, or being shiny or not: the plant is highly variable. Sometimes woody free standing, sometimes climbing/vining. Leaves on the same plant can be smooth edges, serrated, or heavily indented.
