£1100 take home a month isn't great, I think everybody realises this. Remember, though, this is a starting rate and there is still the performance bonus element to it although who knows what this might look like.
As an aside, from what I have heard, there are IFCE managers who do not earn a great deal more than this. I remember hearing £1300 take home not so long ago. That has got to hurt too!
