I was pulling levers on a dredge on Salt Lake in Utah in 83/84, and with there being a wet few years and water rising the union was short of qualified dredgermen and especially levermen.
So we worked 24/7 building the leves for the solar evap. ponds as they were losing millions of dollars in rich brine back into the lake.
We only had 2 levermen on my dredge so we split at 0700 and at 1900, but with 3 crews on deck,
The overtime scale was straight time for 8 hrs, x1 1/2 for 2 hrs and x2 for over 10 hrs., or sat was x1 1/2 for 8 and everything over that and sunday was x2.
The crews working regular 8 hr shifts were taking home about $500 a week, I was Tax Exempt which is really not illegal but it is frowned on by IRS, so I took mine home , which was over $2500 a week and when I reverted back to paying tax as I did every year for a few months, they hit my check for over 62% of my gross so cut me to less than $800 a week. Not really fair as it takes away your drive to get ahead..
