Mistakes to Avoid at a New Job

The first month at a new job is a whirlwind of excitement and nervousness. Once you have officially been hired, it’s important to take a step back and really think about the things you'd like to accomplish in your new role. It’s equally important to know the things you should not do in your first 30 days. Below is a short list of mistakes to avoid, courtesy of FastCompany.com.

Social Media

Two of the mistakes to avoid in your first 30 days involve social media. First, be careful about what you post online when talking about your previous job. Don't post things like “I'm so glad to be leaving,” or “I'm finally free of this place.” It’s important to show grace and humility, even if your old job was the worst. The things you post online live forever and help to shape the impression your new employer has of you.

The second social media faux pas is being too quick to add new coworkers as friends online. Doing so could seem insincere or disingenuous. Slow down and be smart. It’s OK to use LinkedIn to connect on a professional level, but be careful about adding them to your Facebook friends list too quickly. Make sure these are relationships that will last. Here is a good rule of thumb from FastCompany.com: “The more personal information that’s revealed on the social media platform, the more time you should wait before engaging with your colleagues.”

Defining Your Role

FastCompany.com says to treat your first 30 days as the “ask anything” period. Your natural reaction might be to just lay low for a while and let things come to you. Instead, engage with your new coworkers early and often. If there is something you are unsure on, ask someone for help. It’s better to ask questions early on instead of waiting several months when you should probably already know the answers. Consider setting up one-on-one meetings with your coworkers to go over your new responsibilities.


Hopefully your new employer will offer a great benefits package. It’s important to know what’s available to you and make your selections as soon as possible. Most employers will give you a certain time period to register for health and other benefits. Don't wait until the last minute to sign up when you might be rushed to make a decision. Learn about your new employer’s 401K options, as well. If you're unclear on any of the benefits options, set up a meeting with a human resources representative.
