I used to be a professional chess player. Over time I stopped playing competitive chess. Now I dare not enter a chess tournament for I will be humiliated by novices who used to look up to me. So I play for leisure instead.
Same thing can happen to your professional skills which you use to generate income. Without continued use all skills gradually diminish. The only way to remain sharp is through deliberate practice. Try offering free services during lockdown to remain proficient. Many people could use a helping hand in these tough times. Better still use the lockdown to develop complementary skills which build onto your existing skill set. Teach other people what you know. The best way to learn is to teach.
Whatever the case make sure you don’t lose your valuable skills just because the job market has tanked. You can still be of valuable service to humanity by actively deploying your skills.
