Re: not "sacked"
Here's a bit of history on what those terms mean... (if anyone's interested :p )
To be fired: Your tools are burned so you cannot work in that field again (until you replace the burned tools, anyway)
To be sacked: To be given your tools in a sack and told to be on your way.
Redundancy: The post you hold is no longer required. You might be offered redeployment or, if no suitable post is available, be paid off and 'let go'.
To be let go: See being Sacked.
So... unless they're being offered redeployment, then they are, in effect, being sacked...
