I wear gloves when developing prints or toning, not the type that Doctors and dentists wear, just plain kitchen gloves. There are two reasons, one, to keep my fingers dry so that the when I handle paper during a printing session there will be no risk of contaminating the next piece of paper. No matter how well you wash and dry hands after being in fixer you cannot totally remove it and the risk if marking unexposed paper is high. The second reason is that I hate to have stained and dirty finger nails due to the effects of chemicals.
When I have taken the print through the dev, stop and fix I rinse my gloved hands in warm water and dry the gloves on a towell to ensure that I have no carry over of chemicals.
