You know your employer better than we do but you might want to keep in mind that walking people out does not necessarily mean that it's unpaid. EVERY company, without exception, that I have ever worked for would always, on the rare occasions that they found it necessary to ask someone not to work out their notice, pay them. My employers were by no means unique. Many, many companies will voluntarily pay for unworked notice time even though they are not required to by law.
