Jon is a lawyer's lawyer. Between his insatiable desire to assist his clients in achieving their goals (which he did without fail), his compassion, empathy, and inimitable wit, Jon has clearly entrenched himself as a beacon of the employment bar. What Jon lacks in White Shoe pedigree, he easily mak...es up for in his unique and innovative approach to solving the most intractable employment disputes. His seering intellect and sense of humor make him my first choice for handling employment disputes. He ran circles around opposing counsel from a global employment law firm. No case is too big or too small for Jon. Jon's ability to understand people-- the relationships between the parties--ensures an efficient resolution to issues.

I consulted Mr. Sack about a termination issue after returning from maternity leave. Mr. Sack responded to my request to speak within minutes and when we spoke, he listened, was compassionate, and gave me incredible advice on what to ask for and how to ask. Thanks to our conversation, I ended up wa...lking away with a generous severance I am very happy with. Recommend 10/10

I am impressed by Jonathan’s professionalism and business strategy used on my case. He is also very responsive which eliminated my anxiety during the whole process. With his extensive experiences in employment law, Jonathan provides an advantage to help the people who have been treated unfairly by th...eir employers. Furthermore, due to his passion to help the mistreated employees, he was able to obtain compensation on my case which was viewed by other employment attorney as an impossible and difficult case. Thank you, Jonathan, for helping me to close such unpleasant chapter.

First and foremost, Jonathan got me the positive outcome I asked for at the beginning, and then some. He is results-driven and working with him was the greatest decision I made in connection with leaving my previous employer. I was referred to him from another finance professional, Jonathan was incre...dibly knowledgeable and willing to walk me through the entire process. As he was my strongest ally throughout my separation negotiations, I will be his biggest vocal proponent for anyone needing legal representation for an employment dispute.
