Hey Sine,

Just because your workplace doesn't currently use Perl, doesn't mean Perl itself isn't of importance, because plenty do.
You should of course install Perl yourself on your home machine(s) and learn it for yourself.
Once you build up a decent knowledge base of Perl, you will begin to see processes at work that
you can automate using Perl, bringing efficiency to the workplace. Not only that, you may even get creative and begin to see other non-work related applications that you can create yourself because Perl is extremely flexible from design to implementation.

I highly recommend Perl as it stimulates the mind, the syntax is not uncommon, and you learn more about different environments due to its wide application possibilities.

Oh yeah, Perlmonks.org is a great learning environment as well.
