Yea,
It took me three tries 40 years ago, however I have had a good career and will be retiring with a very good pension and 401K type plan!!
Don't give up. If you want to operate construction equipment, will travel, and have some skill after your training you will do well!!
The shortage of operators is here now!!!! Local 66 is building a new training site class room and shop building. They most likely build the shell cracker plant in Beaver that will take seven years and 10,000 construction jobs to complete.
IUOE 66 takes applications usually in January & February of the year. & is very competitive. They want the smartest and most trainable people.
You won't be just driving a backhoe around. Wages contractor pays they want very skilled operators!
Don't give up the first try, you get more points every time you apply.
Good luck!!
