ELI5: How do we know that worker ants are female if they don’t reproduce? Do they have reproductive organs that simply don’t work?

Ants have sex chromosomes just like other animals. So it is possible to genetically determine if an ant is male or female by looking at its chromosomes. And if you do this you see that worker ants are all females but they never get the hormones that cause them to reach puberty and get sexually mature.
