Trap
its a bit of a trap though cause you only get paid if you work over your maximum hours which is what 148 or something.
so its unlikely that you would actually be paid for the days you give back unless your total hours for the cycle go into overtime.
have to read everything those SD people put out twice to make sure you understand otherwise its like the retention contracts that say one thing but mean something totally different.
If you volunteering to give away your off days make sure you going to work full max hours and run into overtime - but wait you have to give them notice before end Jan when no one knows what teh rosters will look like in Jul. mmmm
