Remember in 1999 when everything got renamed to millennium something, Millennium Food & Wine, Millennium Pizza, Millennium Barbers and so on. I swear this shop was just called General Store a few weeks ago. I wonder if this is because the lockdown restrictions stipulate "essential" stores can stay open. Hardware stores can stay open anyway which probably covers this shop, but the term essential might just creep in and stick.
I often think the same about "key worker". There's no strict definition right now but there's some sort of understanding of what it means. How will it be used in 5 - 10 years time? Will staffing agencies be advertising for key worker jobs? Will politicians campaign for better conditions for key workers? Key worker tax relief? Remember when "hard working families" was a popular, misunderstood and overused term by politicians.
Will be it be weaponised by tech platforms and the gig economy?
