Since I have no job, job boredom is not a problem anymore. But at one point in my life I worked in a factory making vacuum bottles, aka
Thermos bottles.

I ran the machine that welded little glass tubes to the end of the bottle, so that in a later step, the air could be vacuumed from between the double glass walls. The problem was that I was standing in an area where the temperature was over 100 degrees F and I was repeating the same movements every six seconds. Ten times a minute, I would take a bottle off the line and put it on the machine. Then I would take another bottle off the machine and put it one the line. Repeat, repeat, repeat, 4FRNFR.

But I wasn't really there. My mind would wander thousands of miles. I would think about places I had been and places I wanted to go. I would go over past and future conversations in my head, and creat plots for stories I planned to write someday. I would think of funny things that happened recently, or sometimes a long time ago. I worked an 8 hour shift with a lunch break in the middle and a ten-minute coffe break ever two hours. The noise level was too high for any real conversation and there usually wasn't anybody close enough to talk to anyway.

I was there for seven months between the Army and the beginning of my first year of teaching. It made teaching seem like a dream job. I never suffered from job boredom after that. Not even when I took summer jobs like painting classrooms or working in another factory.

So I would suggest that if a computer job is boring, you should put something job related on your screen and let your mind wander. Works for me.
