Different personalities in every office

Offices are very interesting places and as different as our faces and fingerprints are, so do we find different personalities in an office. The various office personalities are;

• The favored ones; These ones are referred to as favored because they get the promotions and perks for seemingly not doing anything. Sometimes, these people are kiss asses/sycophants but more often that not, they are people with a knack for figuring out exactly what needs to be done and working smartly to achieve this hence they come across as 'favored', 'lucky' etc. To be fair to their colleagues sometimes, these people are just in the right place at the right time.
• The 'unlucky' ones; these ones work hard, do everything right and yet they can't seem to get ahead. It's like there's a mark on their head that says 'do not promote them'. Sometimes, these people are working hard at the wrong things, sometimes, they might have made some political mistakes and sometimes, it is just not time. Life happens even to the best of us. If you find yourself in such a situation, it is best to stay grateful and happy while looking out for other opportunities. Remind yourself constantly that you are not a victim.
• The Model employee; If work was high school, these ones would be the prefects. They are model staff in that they wear the right clothes, treat everyone with respect that's also reciprocated to them, have tremendous influence that they don't need to shout to get things done because people love to do things for them. With these people, you admire them, learn from them but never let them make you feel inferior because frankly, they weren't built in a day.
• The clueless ones; These one have no idea what's going on either by choice or fate. They come across as people who show up at work just because they don't want to be idle. It's easy to write off these ones but be careful because they might have side gigs they are working on, like that employee who leaves and becomes a major fashion designer.
• The ones who came for the food; While this is far fetched, some co-workers disappear when there is work to be done and magically appear when it's lunch or fun time. Just ignore these ones, they'll get what's coming to them.
