Jonathan Sack is the “real deal”

Jonathan Sack actually listened to us. He took the time to understand the inequity of our situation. He was the person calling and emailing us in between huge case trials to give us advice. His advice was on point. We had other attorneys shy away from the big bank employee name but Jonathon rose ...to the challenge to do what was right based on principle and ethics. He is sharp and efficient and gets it done without quitting or taking the easy road. When we were in a critical and emotional place, he helped move us toward stability and hope. If you want someone who will stand firm and fight for you, Jonathan Sack is the person you want on your side. We are deeply grateful.

Knowledgeable and Responsive

A contact and previous client referred me to Jonathan Sack. I had a complex separation agreement. Jonathan reviewed the agreement in detail, advised me on my options, and took the time to walk me through everything and answered all my questions. Prior to connecting with Jonathan, the ambiguity and co...mplexity was overwhelming. After speaking with Jonathan, I was confident that I fully understood the agreement I was entering into and left nothing on the table. I would highly recommend hiring Jonathan for any of your employment and labor needs.

Helped me out when I really needed it

I was suddenly let go from my job under shady circumstances, and I was so scared of my company that I wanted someone to make sure that it was actually in my best interest to sign their release and accept their severance. I called several attorneys and they all wanted hundreds of dollars to read m...y release, so it was a breath of fresh air when I spoke to Jonathan Sack. His approach was "I will read your release for free. If all I am doing is whispering in your ear, you don't have to pay me anything because making the business relationship is important to me. If I take on your case and get you more money, I want 1/3 of whatever I get you on top of what they have already offered you." After he realized that they also wanted to enforce an unenforceable non-compete, he said "Let me have some fun with this". I walked away with a release agreement that protects me considerably more than the original one did, and my former company ended up paying out double what they had originally offered me in severance. They tried to do several more shady things during the process, and he stood up to them every time. He's also committed to having an ongoing relationship with me should they try to make any other trouble. I can't tell you how much better I feel dealing with my former company with him as back up. In his words "When you stand up to a bully, they always blink." I'm recommending him to everyone that I can.
