Whether due to bad economic times, corporate politics, or other factors, most of us in the workplace have either been, or will be at some point, on the receiving end of the dreaded future endeavors letter.
Conceived as a somewhat kinder, gentler way of saying you've just been canned, a future endeavors letter is usually worded with something along the lines of "we wish you well on your future endeavors".
In other words its a nicer way of saying "there's the door, and don't let the door hit you on your backside on your way out." Getting "future endeavored" most often will occur during one of those exit interviews where your signature is required on a stack of paperwork designed to avert lawsuits. For the future endeavoree, this is often a necessary evil in order to collect a severance package.
And remember, we wish you well on your future endeavors.
