I don't think it was stressful at all. They do expect a lot out of you but I think it pushes you to strive harder. I love a challenge and the hard work does pay off.
I wouldn't call it stressful, but if there was bad weather as an operator you will be there running the boiler maintaining power.

Personally the stress I endured was the fact that I lived an hour away and during the 4 month long probation period made it difficult due to the traffic getting to and from work.
