It's Not Goodbye
Leaving a role you love can be difficult, but when you are no longer learning or growing, then it's probably time to move on. As the lines between work and life become ever hazier, it's challenging to leave your comfort zone, and it's hard to say goodbye to your work family. I like to remember that usually it's not goodbye when you're leaving a role, it's just so long for now. As I ramp up to go through this transition myself (ahhh!) here are some things I've learned along the way.
Figure out why you are leaving or want to leave
Every time I've transitioned out of a role, or thought of transitioning I've come up with a list of why I'm ready to make that next move. Sometimes the answer is simple such as "there is this amazing opportunity that I will regret if I pass it up!" or there could be a variety of them such as further growth, more significant role, etc... I also find that creating this list helps when you are resigning. Chances are if your team cares about you, they will want to know where you are going, why you're leaving and what you will be working on. It's easier to have these answers prepared ahead of time, especially since chances are you are springing your resignation on the team.
Write a good handoff document
There is nothing worse than walking into a new role and having 0 ideas where anything is kept, where the bodies are, and how to access relevant documents. Put yourself in the newbies' shoes; it's tough to learn a new role without much guidance. I've always been an advocate of writing detailed handoff documents and being open to meetings and phone calls. This will help your old team succeed and make life a little bit easier for the incoming person.
Agree to freelance/finish outstanding projects
Leaving is hard, and frankly, there is no right time to resign from a role. There are always on-going projects and things that need to be accomplished. Upon leaving, I have always agreed to help complete projects and even freelance where necessary after I've officially left the organization. No one wants to make an abrupt halt, and having a smooth transition helps both you and your employer. If you are transitioning into a new role, most employers understand that you will be trying to complete various things within a shorter window than usual and expect you to be called upon for help.
Share contact info
Given that I've worked in Startups most of my career, the companies I've worked with have been smaller and more agile. This means you get close with your coworkers. They become your friends, just because you're leaving doesn't mean it's goodbye. Before leaving, I always ensure everyone has my contact and social media accounts, so they know where to find me in the future. Moving doesn't mean goodbye necessarily, sometimes it just means so long for now. I also make a practice of emailing people I work closely with to let them know where I'm going, who is my replacement and hopefully schedule a catchup once I've landed and settled. It's a great practice that gives you a touch base with your colleagues and lets people know what is up in your life.
Get together often
I've always said that there is no such thing as a hard goodbye. While you won't see your old coworkers daily, you can still get together socially. I always make it a priority to try to see them every few months, to keep up with where their careers are taking them and learning more about what they're working on. You never know when you will cross paths both socially and professionally again, and it's good to keep up with your network.
Changing jobs is tough, but leaving doesn't mean goodbye, it just means so-long for now.
