I've done 4 on 4 off for the last 8 years and I can't go back. Great for holidays as you get 6 full weeks off(24 12 hour days) , take 4 off and you get 12 days

I've done 4 on 4 off for the last 8 years and I can't go back. Great for holidays as you get 6 full weeks off(24 12 hour days) , take 4 off and you get 12 days in a row away from work. technically 3.5 days worked per calendar week saves on petrol too.
