I am trying to work out if I am able to drop from a 5 day week to a 4 days week in my full time job as a Secretary. Before I joined my full time job 9 months ago I was told by the agency I was going to work a 38 hour week. I called the Tax Credit Folk ? most of them are lovely but the girl I got seemed to think I was up to something! And also in a mega rush to get me off the phone _ I was only on for 5 minutes! ? it transpires I am now work a 35 hour week instead of 38 so I will drop to a 28 hour week job if I only work 4 days. The girl gave me guestimates but was really not that nice on the phone! When I asked her the following she didn?t know I am not sure how this system works but I am only trying to find out how much worse off I will be should I drop a day? Also my daughter has just started receiving the nursery vouchers for over three (albeit she is in nursery 5 days a week) but if I did not have this my fees for nursery would be £800 - £900 a month so not sure if they base their contribution on the large figure or just give you 80% of what is left once the governments contribution has been taken off? Also I should state I will be self employed on the day I am trying to drop and also a day at the weekend (so in effect a 6 day week but I will be lucky if I am earning £40 over both days at the start) but I want to get this side of this sorted out before I tell them I am also self employed.
