Limited effect, I believe
As Joe acknowledged this is affecting IT staff only in certain areas and only in some sectors. "Yes, some roles are more in demand than others. It’s front-end developers and data scientists who are seeing the biggest increases, according to Tech Nation." Public sector will see none of this. The grading structures remain the same. The private sector? Lately I've been getting regular e-mails, one this morning proclaimed, "10,000 new infrastructure engineer jobs in London." So I wonder whether this has opened up a chasm of IT staff who now want to work from home while companies want their staff back in the office. Once said engineers bums are back on London office seats, will the wages drop? There's also the effect of IR35 to factor into all this and the people that decided to up sticks and move on.
So to the title of this debate, I have to answer no. There's just too much at play here.
I do recall, at the start of the pandemic, standing outside the office for a smoke, passers by our public sector office would give me the thumbs up, a smile, or some other gesture of thanks for still being at my desk, carrying on being one of the small cogs in the big wheels that needed to continue to turn... all the while crossing to the other side of the road to keep social distance! Strange times indeed. And yes, those occasional gestures of recognition did boost my soul, if not my pay packet.
