On Leave or Not

I know I am leak of time right now. I already know that I have no time to do all the assignments on time. What can I do now? I think I need to consider whether to take emergency leave so that I can finish my job. I just don't want to loss the opportunity. This is hard for me to decide. Either back to work like everyday as usual and let go the opportunity or escape from work and finish my assignments to get pay.

Am I having another optional choice?
