Recently, my employer switched to emailing payslips. However, I have just noticed that I'm being paid a set amount for each month, even though I've worked more and less days (May 20 days, June 23 days). Unhelpfully, the payslips do not show the hours worked or hourly rate. It's very difficult to work out what I'm actually being paid in terms of hourly wages. I believe I am owed money as I have worked 50 hours extra over the last 3 months, but this has not been included in my wage packet. I am reluctant to contact my employer before knowing all the maths, just in case the maths checks out, so am looking for some help in this regard as to how to actually work out what I should be on. From April this year, I have recieved 5 months salary at the same amount. Prior to this, the amount was different each month due to the differing amount of days in the month. I have not been notified of any switch to how I'm being paid or how my wages are being calculated. Please help.
