Top 5 things that will get you bored

There are several things that get you bored and unsatisfied with your job if you constantly repeat them and if these things make more than 85% of your everyday work for a longer period of time.

1. Business escalations - if you constantly fight with unsatisfied customers, failing projects, interpersonal problems, etc. If all of these problems end up at your desk too often, you'll get bored.
2. Repetition - you're constantly repeating previously acquired knowledge and really not learning anything new in the professional sense.  
3. "Disconnected" boss - this may seem awkward, but if your boss lets you do too much on your own, you'll get bored eventually. Monitoring also means that someone cares for what you do.
4. Constant pay - you're getting payed same amount of money for your work every month and no change in any direction will also get you bored.
5. Compensating incompetence - if you often compensate incompetence of some of your colleagues and they're not getting sanctioned will eventually get you bored; regardless of whether you're getting rewarded for it.

Most of these points seem like a regular tasks for some jobs, but if there's too much of these you'll definitely get bored at work.
