user expire and crontab impact

In case a Linux user expires, it seems that all Crontab jobs are suspended from running.

The expiry was seen via CHAGE where the "Password expires" was set to a date in the past.

I'm not the System Administrator of the machine itself, but I have the rights to change these kind of settings, I can login as ROOT and I'm also responsible for all accounts on this server.

So, in that context my question is: what is the supposed action to do as Admin for preventing this case ?

We shouldn't wait until an external monitoring program, which does see the impact of not running of the Crontab job which causes an application to malfunction, to report this. There is a big delay here & that is normal and expected.
