Definitely not widely applicable, but alongside getting your professional certifications renewed while still working, make sure you max out any needed Continuing Education requirements for your certification. My company pays for plenty, offers plenty, and has some freely available on the company intranet. For my professional certification, you can roll over CE hours one year. That means that I'm now finishing up hours I need to study in 2020, which means it would be Jan. 2022 before my certification lapses due to lack of Continuing Education.
