How is it my problem if they need to train more people? Did they decide to take a break just last week? Have they never thought about it?

I don't need excuses, I need the content I provided the money to create at the rate it's always been. I pay the sub on time, you' better deliver on time as well. If your employees going on vacation delays your content by 2 months you are cheap and incompetent. It's not some unforseeable cause that you couldn't have dealt with in time. Figure it out like any othet company does. It's embarassing.

We are talking about SE, not some new company that's just started and absolutely can't invest more time and money that it already is.
