There are jerk supes, just as there are jerk CPCs, jerks in TMU or training or support staff and everywhere else at your facility, just like any job.
Supervisors may not be part of the union, may only work enough traffic to maintain currency, and may have highly variable levels of experience, but don't mistake them for the ones higher up. They know far, far better the reality on the ground than the far away regional offices, and those on Capitol Hill. They have to talk to planes same as us, and receive plenty of pain from high above too. We can't fight the people beside us when we have a lot in common, and much to gain from working together.
We are fixing our anger on people who do not deserve it, and the supes shouldn't be getting angry at us either. We need leaders; the thoughtful and the emotional, the loud and the solemn, leaders from all across the spectrum who have experience with the issues firsthand. They must use their power to tackle the systemic problems that force both CPC's and supes into these awful situations where we're constantly at eachother's throats. Tech as old as time, salaries failing to keep up with inflation, the abysmal staffing, the skyhigh rates of physical and mental ailments, and many more problems we've faced for decades that have consistently gotten worse from systemic dysfunction at the highest levels of leadership at the three organizations we align with; NATCA, the FAA, and the elected representatives of the people of the United States.
And the only way to reach the top is for those at the bottom to lift eachother up.
