Thanks for your question. Qlik Community is open to anyone, regardless of employment. There are some sections of the community and support services through Qlik.com that are only available to paying customers, which you would lose, but the majority of the community is open to everyone.
If you have a work email address listed on your community account, when you change employment, remember to contact firstname.lastname@example.org and ask them to update the email address on your account to another email address that you will have access to.
Let me know if you have any further questions.
Qlik Community Team
