This question already has an answer here:
I am a back end developer for a data visualization tool. I have to work with a coworker who does the front end part.
We established the deadline date to the client (it is a internal client in a big company) and I finished the data process almost 4 weeks before the dead line, luckily
I said luckily because the deadline was this last friday and my coworker never finished her part, she had all her own calculated time and my remained time to finish and she never finished; The thing that bothers me is that she does not have the nerve to tell me, hey, I had this XYZ problem and I could not finish my part.
I am responsible for the project, but she has her own boss, should I talk with her boss? the client is fully aware that I'm finished the back end of the project and I do not know about the front end, but I'm responsible of the project, I am afraid that this can affect me
Actually, one of the reasons my last boss was fired, because he directly complained about this person and her work ethic
Should I talk to her, my own boss, her boss?
