For those that are interested the 20/10 recently being offered. It's not the only roster/days off pattern being consider by SV Flight Operations management. There are a number of other options being considered as well, including 20/14 but if you all jump in with both feet for the 20/10 you'll not see the 20/14 even proposed. Like any offering situation, it's not always wise to take take the first proposal on offer.
Incidentally, the 20/10 option is supposed to be offered with the choice of two month pairings, so the the 10 days off at the end of one 20 day period butts up with 10 days off at the beginning of the next period. This gives a block of 20 days off in one go. It is supposed to go something like this:
Month One. 20 days on followed by 10 days off.
Month two. 10 days off followed by 20 days on.
So, over a two month period the work/days off pattern should look like this:
20 days on/20 days off/20 days on.
Got it?
