Nobody is saying you are not good at your job. In fact, you guys are most likely the best fit. Certainly better than EWA’s.
It seems to me that the OP is saying that EWA’s got a minimum of training months ago, and were able to hit the ground running. And, in short order, his/her team was able to outperform BAU metrics. Maybe it was a small team, or maybe it was only certain metrics… maybe it was the same standards you guys are held to. The anonymity of this forum dictates details be withheld.
In light of this, it is suspicious that the people who do this on a regular basis need training after only being away from their job for 2 months. I would have to agree that it looks like union work avoidance. Something I’ve seen firsthand with many unions. Regardless of what trade the union covers, they are good at their trade. However, they are masters of work avoidance on all levels.
And, while we’re at it… We live in a world where companies seek out, and pay top dollar for talent and skills they require. if you need an organization devoted to convincing you employer that you are worth X, Y, and Z… I hate to say it, but you probably aren’t.
