|There are plenty of outrageously inept, dissatisfied, and negative managers whose offices have more lush greenery than a rain forest. For your manager to even hint that your attitude is killing the foliage in your office means that your plant is actually evaluating your performance, an approach that sits somewhere near the top of the ridiculous scale. |
Now, there are people who say that if you want plants to thrive, you should be nice to them and talk to them. That of course explains why so many plants thrive on the freeways and turnpikes directly adjacent to semi-trucks, honking horns, exhaust fumes, and discarded garbage.
The only useful piece of data in this encounter with your manager is that he thinks you have a negative attitude. You should dig further into this assertion, starting with an honest self-assessment. You should then meet with your manager.
It will be important to emphasize that the best measures of your attitude are your performance, productivity, and ability to inspire and motivate those around you. Try to bring some specific performance data that reflect your attitude, efforts, leadership, and drive.
Your attitude has nothing to do with your ability to inspire your plants to bloom, but it has a great deal to do with your ability to inspire your employees to bloom.
