Surely the way to fix the unread ability of the deck/side markings, is for all pilots to agree on a set standard. Now I'm sure that there already is a standard, they seem to have standards for everything else, so you simply fly out to said rig, approach, sorry deck markings are not up to standard, turn around and fly home.
I would love to see the HR person that will stand down a pilot for WANTING to comply with company standards. Get yourself a really good lawyer, and get enough money out of them, that you then decide if you want to go back to work.
I know it sounds silly, but if all the pilots in said company, said, gee that could have been us, and they have been stood down for what reason? Then maybe they should all stand together.
It won't take too many workers, not getting on the home flight after a shift for them to suddenly make everything spik and span!
They have their standards for a reason, fly to them, remember it's no longer the 80's or 90's when you made a mistake, discussed it with the boys over a beer and everyone learned from it.
