Surely you can do the math, right?

Your first job required you to work 58 hours a week for $2900 and no additional bonus.

Your next prospective job requires you to work 47.5 hours a week for $3250 with prospect of bonus.

Even if we take the bonus out of the equation, your income per hour increases from $12.50 an hour to $17.10. Your real pay hike would be 30+%.

I would say do something with your extra income and free time, like get additional professional certification to diversify your skill set since you have quite ordinary qualifications and your best asset currently is probably the fact you hold a pink IC.
