Reasons for Being Given Deadlines
Time is something that is not always on the side of any employee or worker. While it depends on the nature of your job, chances are you will be having problems with deadlines once paper work starts piling up. And once you fail to meet these deadlines which are pertinent for departmental efficiency, chances are you will be bear the brunt of the blame for its incompetence.

But while this may be an issue that many would blame on being overworked, there are some people who always believe in “you can always continue tomorrow” or perhaps “the deadline is far off”. Rarely would you see people today finishing ahead of time when it comes to deadlines. They believe they have all the time in the world to kill.
Normally you would be given a week or two to compile and finish a report on something like sales reports or revenues for a certain period. Sounds easy to do but it is really getting the data that will bear the brunt of the job as well as formatting it in a way that will make your superior understand the current performance of your company for evaluation. Even the seasoned employees who are used to making reports should not take this task lightly. This is because they also have to review and make sure that everything reported is accurate since one wrong figure will be critical for the entire report.
Hence deadlines are given for workers to adjust. The last day is not the only thing important. It is how you manage your time. Do not be afraid to finish the report early since you need to review it before presenting it.
That is the whole essence of measuring efficiency. It is not about how fast you accomplish your work. It is about accuracy and making sure that you produce what the boss is asking from you.
