Down

Been feeling very down recently because of work. A lot of deadline overrun and delay. I really don’t know what should I do. To help or not to help? If I don’t help and he cant deliver the project on time, it is my fault and not his because I am the project manager and he is the programmer. But if I were to help, I feel very unjustified because he has been playing games everyday during office hours. Why should I burn my weekends to help him with those works that he is suppose do where I could have use the time to prepare for my exams?
