Welcome to the forums.
We do not do people's work for them.
You have a fairly specific brief. Surely you can sit down and think out the advantages of good time-keeping in the work place concerned; equally you can consider the possible effects of bad timekeeping. Having created your lists, write an introductory paragraph stating what you intend to show, summarize your thoughts, and finish with a comment about your findings.
Post the text and someone can then comment.
