hang on paid a month in hand .. you mean you work the month of December you get paid end December, then you have to work the month of January to get paid the month of January, right?
So you worked in December .. did you pick up a paycheck before christmas (or at end of December) if you did then you are evens with your both
you will have to work february to get paid in february
I am assuming you took January off as unpaid leave rather than holiday though?
or have I got totally the wrong end of the stick?
