This question already has an answer here:
So I have this giant project that has a ticking deadline of a little under 2 months. My boss (IMO) over promised on the timeline to the client by a mile and let the client set the deadline rather than the amount of work. About a month ago he hired another dev to help me out realizing I couldn't possibly do all the work myself. I'm already pulling regular 10 hour days.
The guy he hired is just a mess though. On friday we were supposed to have an internal demo ready however when I started going over things with my partner on thursday it became glaringly clear he didn't have even a fraction of his work done.
In the afternoon I had other things I really needed to get done and asked him if he felt comfortable implementing the rest on his own and he blatantly said he didn't know where to begin and that I'd done in a few hours what took him almost 2 weeks to do.
I've tried bringing this all up with my boss and point blank told him that I don't see us making the deadline. He doesn't seem to be open to the input though and has now insisted that I just go over my partners work every morning and evening to see what he's done. I can understand that he probably doesn't have time to look for and hire another dev but am running myself ragged trying to manage everything. We can't make the deadlines he's setting and I don't know how to tell him that just because he wants it done by a certain date doesn't mean its possible. Especially with my limited time and my partners limited knowledge.
