They need those offices to be full and the demand to be high for commercial real estate. If commercial real estate becomes less valuable, the banks who own and finance that real estate lose a ton of money.
If the offices are empty, the companies can’t even sell the real estate because other companies won’t want to buy it either. This will devalue commercial real estate properties as a whole, leaving businesses with a lot of high interest loans to the banks for assets that are worth much less than the loans they took out.
When those companies go under, The banks will be left with a bunch of commercial real estate that is essentially worthless.
So you’re all working for the bank so your bosses can pay the loans for the real estate for your office. The furniture inside the office itself is worthless.
