Not every workplace problem is “just part of the job.”

Harassment, discrimination, and retaliation can show up in ways that are not always obvious. Sometimes it starts with a comment, a change in treatment, or something that makes you uncomfortable but is difficult to put into words.

If something at work doesn’t feel right, pay attention to the pattern. Write down what happened, save relevant messages or emails, and keep track of important details.

You deserve to understand what is happening and what options may be available to you.
If you’re questioning whether something at work has crossed a line, it may be time to learn more about your rights.

You spend a big part of your life at work. You deserve to feel respected while you are there.

If you are being treated differently, harassed, overlooked, or made to feel uncomfortable for speaking up, do not assume you simply have to accept it.

Sometimes, the first step is understanding what is happening and knowing what options may be available to you.

Your experience matters. Your rights matter.
If something does not feel right at work, take it seriously.

New Jersey workers deserve to be heard.
Because we don't just handle cases.
We advocate for people.

Do you know what your employer is required to do if you need an accommodation at work?

A disability or health condition does not automatically mean you have to choose between your health and your job.

New Jersey employees may have rights to reasonable accommodations, but understanding what your employer is required to provide can be complicated.

We break down what employees should know about workplace accommodations, employer responsibilities, and when an issue may become a legal concern.

Learn about your rights as a disabled worker in New Jersey. Discover what accommodations employers must provide under the ADA and NJLAD, including job restructuring, schedule changes, and more. Understand the process for requesting accommodations and when an employer might deny a request.

Are you working off the clock? ⏰

Maybe you’re answering work messages after your shift. Staying late to finish a task. Or arriving early because there’s still work to do.
If that time is not being recorded or paid, it may be worth taking a closer look.

Under New Jersey wage and hour law, employees covered by the law generally must be paid for all hours worked. Employers are also required to keep accurate records of hours worked.

Your time matters. Know your rights.

When workplace power is abused, employees are often the ones left dealing with the consequences.

But you have rights at work, and your employer has legal obligations.

If you’re facing workplace discrimination, retaliation, wrongful termination, harassment, or wage violations, understanding your rights can help you determine what steps to take next.

At Mark | Lavigne, LLC, we represent New Jersey employees in employment law matters and work to hold employers accountable when workplace rights are violated.
