I am a results-oriented, energetic advocate for my clients. I am passionate about representing my clients. As most cases come from word-of-mouth referrals, I am proud of my reputation built one client at a time. Most clients are faced with a difficult challenge in a critical part of their lives: their jobs and careers. I am competitive and look forward to taking the fight to the employer to redress unfair and illegal actions. I align our firm's fee arrangement with the client's desired outcome so that there is an identity of interest in the result sought. My success is defined by each client obtaining the desired outcome as a consequence of my effective counsel. Most of all, I love what I do, and that is helping people and seeking fair results for clients who deserve better treatment from their employers.

Goog guidance
Getting laid off is like having the lights turned off on you. Mr. Sack was like a flash light - he mapped out my options clearly and detailed pathways towards a reasonable exit, with zero minced words and zero nonsense. It was valuable to have an honest opinion on where I stood legally.

Provided Help During a Difficult Exit
Jonathan was recommended to me by a friend when an exit from my employer ended up not going as smoothly as hoped. Jonathan got on the phone with me within hours (on his vacation) and provided consultation. I hired Jonathan, and he was very responsive and helpful. Though we were unable to get as much ...

Didn't handle case properly
Didn't handle case properly. He totally misjudged the situation, which resulted in very poor compensation from an employment termination case.
Some clients have an unrealistic sense of what their case is worth. With a contingency fee arrangement, our interests are aligned with the client's interests. We always try to zealously represent a client to maximize the outcome and achieve the client's goals.
"Jonathan is one of the most professional, effective, and direct attorneys I have ever met. His knowledge of labor and employment law is vast and very respected. You can't go wrong having him on your team."
