All In The Same Boat

When everyone is facing the same challenges.

 See faring expression dating from Ancient Greece. During a storm, every man needed to do their best otherwise they would all face the same fate. This has evolved to be used figuratively in wider use.

 Ex: Come on people, lets work together, we are all in the same boat here.

 Spanish: Estamos todos en el mismo barco

German: Wir sind/sitzen im selben Boot
