What do you think of this?

You own a company, and have 200 employees. Most have been there for 10, 15, 20 years, some have been there for 25 to 30 years. Then you have employees who have been there for 5 to 8 years. Generally, people are nice to each other, but you have instances where some people might not have great attendance, or some people might not be the best at every job, or some people might be late 2 or 3 times a week, or some people might call off every monday and/or fridays.

Do you let go the people who are late, or who call off every monday/friday, or do you keep them because they are nice?
