An Industrial Maintenance Worker has a tiring job, as well as an Executive who has to work for long hours.
An Executive has high salary, while a I. M. W has the possibility to have rather bad pay.
To be an I. M. W you don't need to have university qualifications, compared to an Executive where you must have them.
If you are an I. M. W, you can have not only night shifts, but also split shifts, whereas an Executive has no personal life.
