Wow, £3225 this month. Thats good and works out to £38,707.73 annually. But hold on, aren't you employed/contracted for 6 months? In which case its more like £19,353. After tax I guess you're taking home just shy of £2,400, or £600.00 per week. Over 6 months that doesn't really add up to a hill of beans. Good old CTC/EZ - screwing 'wages' down below the national average.
You should show a little more integrity and maturity.
