Rant: i have a software firm, recently got a new project, found a freelancer to work on the project.

He is a very good developer but he works on the project only when he wishes to work and I am left to answer the clients about project delays.

It's so frustrating that I can't get angry on him otherwise he will leave the project and on the other side I have to answer clients. I am stuck with all the tensions in the world.
