^^^^^^This is one of the biggest liabilities to any union and a key weakness of a seniority system.

The guys with all the seniority are usually the least affected by and most likely to vote yes for any new TA, because the BEST way to get a union riled up is to mess with the top of the food chain. Mgmt knows this and avoids that accordingly.

It's been said before but the changes to medical info and sick leave in Sec. 14 needs to be hammered home to the top of the seniority list!
