using nohup in a script but unable to see status of backgrounded jobs

I have script that does some stuff but the key part is starting a series worker scripts it created like this:

#!/bin/bash

...

mapfile -t workers < <(find workers -name '*.sh' -printf "%f\n" | sort)
for i in "${workers[@]}"; do
  nohup workers/"$i" > "nohup.$i.log" &
done

Since the nohup was executed in the script, running jobs -l on the shell I used to run the script gives no results. I am looking for some ideas to see the status of the worker scripts, are they running, finished, errored, etc?

Isn't the trailing '&' somehow defeating the purpose of 'nohup'?

Do you expect the master script to terminate before the jobs?
If not you could trap SIGUSR1 and make that print "jobs -l"
If yes, you could wait for all jobs before you terminate the script?
