I feel sorry for the F/As who doesn't support SSM. Awkwardness on the other end of the cart with the potential for it to impact adversely on the creation and viability of the teamwork so critical if things go wrong. Ultimately that could impact all of us in the crew.
Precisely why this political stuff has no place in the workplace. Just imagine a situation where someone alleges harassment or bullying because he's NOT wearing this ring. Maybe someone gets stood down over an incident, even?
You want to support this stuff in your private time, fine. But not in the workplace. Workplace is for WORK. Clifford and co have definitely overstepped calling for staff members to show support by wearing it.
