Our engineering team has developed this ritual where we estimate tasks optimistically in planning meetings because everyone wants to seem capable, then we all quietly work nights and weekends to hit the deadlines we set for ourselves. The whole team participates in this fiction and I don't know how to be the first person to say the numbers don't work.
More people experience this than they realize.
Your team lowballs estimates to look good, then burns nights and weekends to keep up, and you're afraid to be the one who says it.
