More creativity needed here. Wait until you know a very big project is due. Preferably on a Friday. Then the two of you schedule off. Or if you have clients who come to the office....wait until a visit is planned. Then at the last minute schedule off. Leave a list of instruction as if they were school children.

I had a boss once. I was the only woman on the team. He would ask me to do the "girlie" stuff. One day he asked me to make his tea. Who knew you are to use HOT water in making tea???
