The company the size of Disney? The company I work for micromanages sales forecasts to the FREAKIN HOUR at times of the year. OpEx spending can be clamped down within hours. Approvals to release new spending are happening non-stop and everything can be slowed or paused. This is a Fortune 100 company with over 70k employees and 50 billion a year in revenues. OpEx spending is like a faucet... you can slow it down with just the click of an email. There is inertia of course due to things in motion, but the decision logic is simple.. and it's effective.
How effective the changes are depends a lot on your type of business and where your costs come from. If you have high fixed overhead due to fixed labor and assets... you're not going to move the needle much. But if you are a scaler business that has lots of discretionary spending or flexible labor or operations.. you can make big change. Freeze all contract labor in the offices, freeze travel, eliminate overtime, pause any new non-critical capital spending, scrutinize discretionary spending. All common tricks even in simple white collar work to manage expenses when revenues are projecting shortfalls.
What? Have you ever even worked in a big corporation? That statement is ludicrous from even a white collar corporate world... Never mind the obvious examples how Disney manages costs in their parks. Staffing, operating hours, deferred upkeep, limited operations, limiting things like contractors, limiting entertainment, etc.
"tightening the belt" is something every big company knows how to do.. and Disney Parks has shown countless times they are well versed in the tools as well.
