In the past 11 years ive sailed tankers with various companies, weve treated cadets how they are supposed to be treated. They are onboard to learn, not to be used as cheap labor (hence the 30/day rates) They stand watch (put in as much cel nav in the nav workbook as humanly possible), and do all the dirty works that mates do (hook up hoses, gauge, sample, tank clean, swing blinds, etc). They are not used to clean heads, OS/ABs who get paid 300/day clean heads.
They should have learned how to clean heads during freshman year/freshman cruise anyways
