It’s not your grandparent’s retirement.

The retirement years look very different in the 21st century. Instead of parking themselves in a rocking chair or becoming regulars on the golf course, 55% of today’s workers are planning to continue working after retirement.

While some seniors need to work for financial reasons, many others choose to work in order to stay active and maintain a sense of social connectedness.

At the same time, older workers often look for different things from a job than their younger counterparts. Most want fewer hours, less responsibility, and less physical rigor than they experienced in their 40-hour work life.

If you are a retiree considering a part-time job, you’ll also want to take your experience and interests into account. In many cases, the knowledge you gained in your past working life can be a valuable asset when looking for a new job. You also want to consider whether high pay is a necessity, or whether you could be happy with a lower-paying (but possibly more satisfying) occupation.

Here’s our breakdown of some of the best jobs for retirees right now.

Consultant

This job allows you to use your life experience to give professional advice to companies. If you’re an expert in your field, you may not even need any additional education or training. It also has the potential to be highly lucrative.

Tutor

Retired teachers can use their expertise to help students pass their SATs or bring up their grades, especially in challenging subjects like Math or Foreign Language. You can even tutor online, from the comfort of your home.

Tax Preparer

As a tax preparer, you’ll need to be dedicated to working hard throughout the tax season (winter and spring), in order to enjoy well-earned free time throughout the summer and fall months. You can start out as a volunteer with the IRS, and then strike out on your own as a professional tax preparer once you’ve learned the ropes.

Pet Sitter/Dog Walker

If you love dogs or cats, this is the perfect job for you. You can get paid to take dogs out for walks while their owners are at work, or caring for furry friends while their owners are on vacation.

Security Guard

If you can handle the physical demands of the job, this might be a great option, especially if you have previously worked in the police force or the military. In some cases, you may be asked to patrol a given area; others might simply involve monitoring security camera footage.

Sports Coach

If you have a passion for sports, working as an athletic coach is a great way to channel that love. You can find coaching positions through youth sports organizations, schools, and community centers. Another perk: you only have to work during the season, and get the rest of the year off.

Customer Service Representative

There’s always demand for customer service positions, and some even allow you to work from home. Jobs like these are ideal for anyone who is used to serving the public, especially if you are skilled at coping with difficult people.

Blogger

Websites and blogs are always better from the perspective of senior contributors, as shown by the popularity of sites like Senior Planet and ElderChicks. If you’re creative, good with words, and have the wisdom to share, consider starting your own blog or “vlog” which can eventually lead to opportunities working as a blogger for established sites.

No matter what your skills and interests are, you can find the perfect post-retirement part-time job to keep you young at heart.
