How to know when it’s the right time to leave your job, according to a 20-year HR vet

• Jamie Jackson worked in HR for over 20 years and is now a podcaster and consultant.
• Jackson said when you’re no longer engaged or growing at work, it could be time for a new role.
• Updating skills and preparing a job search toolkit can aid in career transitions.

This as-told-to essay is based on a conversation with Jamie Jackson, a 43-year-old podcaster and consultant in Nashville. It has been edited for length and clarity.

As someone who has worked in HR for over 20 years, I’ve had this conversation countless times. People often confide in me, saying, “Jamie, I don’t know what to do next.”

They feel stuck in their roles, want to advance, or are considering a new job — but that can be just as scary because it means stepping outside their comfort zones. I’ve been there, too, wondering whether it’s time to quit my job for something new.

If this is you, here are four key signs you’ve been in your role too long and what you can do next if you need to make a change.

1. You no longer feel motivated

Your engagement level is a good indicator of whether you’ve been in your role for too long.

For example, you may have previously felt engaged in meetings but now find it harder to do so because you no longer feel motivated.

Or, perhaps you once enjoyed conversations with coworkers at the watercooler or over coffee — asking about their weekends or holiday plans — but now you simply do what you need to do and move on.

2. There’s no room for growth

Another sign is feeling stagnant in your growth.

For example, I once worked at a company for five years and kept being promised a promotion. Over time, it became clear it wasn’t going to happen — they didn’t see me moving up.

For a long time, I believed their promise was coming, but it never did. To advance, I realized I’d need to change companies because the growth I wanted wasn’t going to happen there.

Sometimes, there simply isn’t room for growth, and when that’s the case, it’s a clear sign that it’s time to make your next move.

3. Your feedback has plateaued

Or, you might find yourself hitting a feedback plateau.

For instance, you may consistently receive the same performance reviews, with your manager saying that you’re meeting expectations but not exceeding them — suggesting you’ve reached a stopping point.

If you’re thinking to yourself, “I don’t have anything else to offer. I’m doing the same job I was doing three years ago without additional constructive feedback or recognition,” it might be time to switch roles.

4. You’re burned out

Another sign is burnout. In the past, I had a job where I felt physically sick going into work.

I remember one time needing to pull over to the side of the road to puke because I was so stressed.

As I sat in a parking lot trying to compose myself, I thought, I have to find another job. I knew my mental health was more important — but as I didn’t have the luxury of quitting on the spot, I found another job first.

For others, there are times when environments are insanely toxic, and they need to get out immediately — and they should, but when possible, it’s important to have a plan in place.

Either way, burnout or feeling physically sick from work might be a sign that it’s time for a change.

If you realize you’re no longer happy in your role, you need to do some self-reflection

Ask yourself, what are my goals? Where do I want to be? In your mind, try to understand where you want to be in six months, a year, or even further into the future.

Do you need a new title or a promotion, and if so, how do you get there? Before doing anything, it’s really important to understand what you want. Then it’s time to take aligned action.

Brush up on your skills

Maybe you’re perfectly content with your current role; you just need to be challenged more. By learning new skills, you can push for more responsibilities.

You can use resources like LinkedIn or YouTube to brush up on skills like Excel or explore additional training or certifications offered by your current company. New skills can help you stand out in your current role or make you more appealing to potential employers.

Get your tool kit ready

If you’re looking to land a new job, you need to learn new skills and prepare your toolkit.

This includes updating your résumé, refreshing your LinkedIn profile, and researching the salary you should be making.

When you start looking for a new job, knowing your market value is key — especially if you’ve been in your current role for a while and aren’t sure what the going rate is. From there, talk to your mentors, colleagues, and friends, and let them know you’re looking for something new.

You might say something like, “Hey, I think by March, I’m really going to start looking for another job — so can you keep your eyes and ears open?”

That can really help.

December isn’t the easiest month to get a new job, with the holidays and people taking time off. However, January can be a better time as companies enter the new fiscal year — new budgets and new positions are being rolled out. But you can always be passively looking.

Some of us are content where we’re at, but if you’re no longer interested in stepping up or taking on new challenges, it might be time to reassess your role.
