Freighter working routine?

[Mike Oxbig]

I am thinking of applying for an FO position on the freighter fleet with an LHR base so can anyone give me an idea of the working routine? Is there a fixed roster and if so how many days away a month? How many hours does one fly a month and over the course of a year? Does one end up flying clockwise/anticlockwise around the world or east/west and back again, etc?
Appreciate any info.
Thanks.
:ok:
