Nigeria is unique in very many ways and if you work in an office, you could easily identify the following three categories of workers;

1. The Wheel Barrow staff:
These are the push and move members of staff. They work only when "Oga" is around. They needed to be reminded of what to do at all times.
In fact these class of workers hardly use their initiative and are hardly innovative hence, they win the Title; "Wheel Barrow". When you push them, they move when you stop pushing, they stop going.

2. The Eye service Group;
These are another group related to the first group. The difference is that they work real hard to be noticed by their boss. When the boss is not around, their productivity is very, very low. Unfortunately, these group get promotion and salary increment easily because we all love sycophancy. They literally worship their boss. That is the dream of every boss; they carry his bag, polish his shoe, clean the table and do whatever the boss ask them to do. When the boss is not around, they call him "USELESS MAN"

3. Open minded group
These group have passion for their job and very productive. they don't work to impress, they only work to satisfy their conscience. If you work under them, you would like the job. They might not easily get promotion but they are the happiest members of staff. They do their work without any grudge or complaints.

Not exclusive; kindly add your own

4. The complainer.. This type can complain for africa. They can complain you to the boss and equally complain the boss to you
5. The famish staff.. This type eat whatever they see around so long as its eatable. They always go with food from home
