If a software engineer leaves a Tech company and then goes and works for a oil company are they a tech worker still? Or are they now oil workers? I don't thin

If a software engineer leaves a Tech company and then goes and works for a oil company are they a tech worker still? Or are they now oil workers? I don't think mainstream media would consider that example as "tech worker" when the software person might be doing the exact same work. Mainstream media will likely use the words "tech worker" when referring to the 10,000 people at Meta that will be let go. There could be some food service people in that layoff. I bet articles with the words "tech worker" get more clicks than if they said a bunch of accountants or HR people were let go. Labels are mostly meaningless. Its like a couple homeowners arguing about what type of grass they have in their lawn.
