Is there some "explain it like I'm 5" overview of why this tram is almost complete but due to some labor action, we can't use it for another 16 months?

In 16 months, a lot of traffic, noise, and air pollution will be generated. And if this labor dispute is projected to be dealt with by Jan of 2026, why can't we bring that date forward?

I'm sure there are valid reasons, but the bit I know just doesn't add up.
