I can only advice you to look at the output of iptables and see if you can figure out why it doesn't work.

The default zone is not selected according to used zones. It is defined in the firewalld.conf file and you can change the default zone with all firewalld tools.

firewalld supports to use interfaces and also sources to activate a zone.

There are overlapping sources. Right now firewalld is ordering zones by names and this also affects the sources bindings of zones. The internal zone is therefore handled before work and trusted.
To make your setup working you can simply rename internal to Z_internal to make sure that it is handled last.
I am sorry, but code to order sources (subnets) according to the size of the source has not been added to firewalld, yet.

Thanks. That explains it. I thought they would be checked in a different order. I solved this another way, by moving ntp to the public zone and deactivating internal by removing the sources.
