While he's well liked by his fellow employees, I frankly can't wait for him to leave. I feel like celebrating. Since he is well liked, I'm concerned that my other employees will notice how genuinely happy I am that this particular employee is leaving. Rise above your personal feelings. Give your employee a positive sendoff.
Employers damage themselves with their current employees when they insult a departing employee.
When a long term employee leaves your organization, consider hosting a going away potluck for him. Above all, don't obviously rejoice in his departure. Yesterday, I learned that he had taped the meeting at which I fired him. He's threatening to sue our company based on what is on that tape. An employee has a right to tape a meeting, unless a meeting is over the phone.
