I was checking my bank and I noticed my wages were down by just over £20 so I checked my payslip online and my national insurance contributions have increased by that amount
I've no idea why as my pay is the same as any other week, any ideas?
Thanks for the replies, seems a bit strange to go from £23ish to over £40 in 1 Week then, I'll query it with HR as its never been that (apart from when there's been a big increase for the week ie blood money etc!)
