Regularly you worked 8 hours a day. If it snowed, you were forced to work 12.
During an outage (when the turbine went offline for maintenance) which occurred 2 times a year, it was mandatory 12 hour shifts, 7 days a week, which could run into a month and a half. Depending on how long the turbine was offline.
We also had to take, and pass the same tests the Nuclear Power employees had to take and pass, but were not compensated financially for.
Steady work, some benefits, it was close to home.
