It depends. If the desired outcome is “wait and see what happens” with no specific timeframe, then a “cool-down” makes perfect sense. If the desired outcome is lower new-hire class sizes. Maybe marketing/education (billboards, Facebook ads, ADs on APC, etc.) would be a better use of union resources.
Personally, I’d rather see my union dues spent on negative advertising, instead of donut parties in the crew room, and do-nothing “cool-down” PUB events at Red Robin.
