Cats usually don't go to work because they haven't been trained to work. Cats are generally family animals and enjoy playing and resting at home. If you notice that your cat keeps going to where you work, it may just want to keep you company, or it may be because it's looking for food or water.
If you want your cat to stop going to where you work, you can try giving it enough food and water , and give it a comfortable place to play and rest. If the problem persists, you may consider consulting a veterinarian or behaviorist to learn more about your cat's behavior.
