It does seem like this is basically what they are doing. The messages employees received did not include the actual paperwork, which the messages say will come in about a week. It could be interpreted as a strategy to "terminate" aggressively but with the option to walk it back a bit if the place falls apart within the week. It's a clever-sounding approach on paper. But there is a human element when dealing with people's livelihoods that might not have been sufficiently considered.
