Bon Voyage... I think?

There have been a number of voluntary resignations at my place of employment recently.  Some off to other jobs - better in their eyes of course, some to take on their dream job completely opposite of what they were doing, others to retire and a couple to tend to their young offspring.  In this economy I think its great, when someone can decide to leave their job, for whatever reason they choose.  My question however leads to the good bye. 

The department that I work for (Human Resources) has this very strict policy to not acknowledge the person's departure if they are leaving to go to another company.  Not acknowledging is actually an understatement - sometimes I didn't even know the person was leaving until days before their last day.  I will have to do some further research on this school of thought, because I've seen departments in the same building celebrate the progression of soon-to-be former employees.  Unlike when someone retires, there of course is this great party, with decorations and a catered spread, or I even had a coworker resign because her husband received a great job offer out of state.  I totally agree that in these situations - food, some cake and punch or even an after work dinner would be in order - especially if they were a valued employee who did a great job!

But - then a part of me says, although an elaborate send off is not necessary for the employee who is mentally screaming "deuces" from the top of their lungs, off to their bigger and better job - an acknowledgement and thank you for their work and skills they brought to the company would be a nice courteous and ethical gesture.  No matter their choice - you can't deny their contributions to the company, you just can't.   

This clearly is not a direct science as to how you part ways with your staff/colleague, because some employees may have not have been the best employee anyway, but a little thought and your best judgement can come in handy when their last day arrives.  Even if it's just some bagels and coffee the manager can gather the team to say thank you for your services and best of luck to you in your endeavors!  OR if the company would be better off without them, an email blast to your team to say thanks and encourage the staff to drop by and say good bye and good luck.

That's not hard to do - it's really not.
