At one major multinational communications company that is Canadian based, they called my whole department including the department head in to a conference room, where a phone was set up without any other personnel from the company were present.
The phone rang and the department head answered it. He was told to put the call on speaker phone and in in a one minute statement the voice at the other end told us we were all layed off immediately with one weeks severance per yaer of service and to clean out our dseks and leave. That was it! NICE COMPANY!
