Aye it's quite unsociable as I often work weekends and find myself sleeping during the day a lot. We get an extra £5k a year as "Unsociable Hours Compensation" though, it makes it all worthwhile
Stress...that's a word I hate. Most of the time I'm under a healthy amount of pressure when working, it only turns into stress if I'm fatigued or if it gets too busy/complex. I get the feeling that my stomach is tying itself in knots and I sweat buckets. However the joy about the job is that once I unplug my headset I can just forget about everything. The stress can put me in a bad mood and I come home a right grumpy eejit but that's once in a blue moon.
I deal with it by being cynical and sarcastic to strangers on the internet as you may have noticed from my various posts throughout these very forums
