I wholeheartedly support the pilots stance & I'm a CSD on longhaul. I realistically know that when we have our next IA, we may not get the same support in return, but even so, I'm 100% behind our "drivers".
Bearing in mind that within the flying community, its a standing joke that our managers & those at waterworld only work (attend?) Mon-Fri, I'm not sure how much impact a protest march on a Saturday will achieve.
All the best,
Matt.
