So drivers are quitting so they can take advantage of the great work rules, benefits, and pensions at non-union companies? Here's a news flash: non-union companies do not have work rules, benefits, or pensions. (There may be some so called work rules, enforced at the whim of management. And there may be some minimal benefits. But pension? Come on.)
Yes, you are right. It is the pretty good job to just sit tight in.
The pension was in trouble in 2006 and it is still in trouble. It's not like anyone's leaving to go to non-union companies for the great pensions they have there. Most drivers in their 20s are not even thinking about a pension. Or know what one is.
I'm not going to argue this here and obfuscate a thread about a change of operations. All companies have problems getting qualified applicants and getting them on board. I was the only one in my "class" that stayed, and that was a well before 2006.
