It depends on what type of work you're doing in the office. If it's just typing over and over the same thing and you don't like what you do then it can get very boring.
But on the other hand if you love what you do such as web design, web programming, coding designing clothes etc then it can be fun.
If you work in an office try and make sure you get an office job that you love doing. If you love doing the work you'll never be bored in your life during your office hours.
