Manual labor in all weather types, but flexible.
Pros: flexible schedule, hands on work
Cons: long days, hot sun
My typical day included cleaning out trenches, assembling valves and piping, burying the lines, wiring up the timer, and running equipment. Sometimes we also installed the sod for the lawn. My boss was great and often had me work on my own while he finished up other projects. The hardest part of the job was the manual labor and being out in the sun all day. The most enjoyable part of the job was being out of the house and playing in the dirt.
