The best example of a pilot union for the most point meshing with a mgmt group is SWA...
As a pilot and even any employee you can be PRO UNION and PRO COMPANY...
its about what is fair to the work force and fair for the company in which they both can grow and prosper in the industry... Its when one or both sides start to act, shall we say GREEDY, that things get out of whack and trust is broken...
There are many examples of this in almost every UNION industry... The auto and airline industries are huge examples of this.
Trust is hard to gain and EASILY destroyed...
