calculating breaks

What formula would I use to calculate breaks automaticaly, for example on an
eight hour shift a one hour break should be deducted, in a six to eight hour
shift half an hour should be deducted. Anything less than six hours and no
break is deducted. I have set up a spread sheet to work out the hours worked
but I need to take break off this, I would rather the spreadsheet calculate
this for me, than me have to input the breaks manually.

Assuming your shift duration is in A2, calculated time is given by following
formula:
=IF(A2<"6:0",A2,IF(A2<"8:0",A2-"0:30",A2-"1;0"))

Since you say that you've already calculated hours worked (decimal number),
then with that number in A1, try this:

=(A1<6)*A1+(AND(A1>=6,A1<8)*(A1-0.5))+(A1>=8)*(A1-1)
And copy down as needed.
