Employment and Labor 50%

We consult with, advise and represent employees and executives in all facets of their employment. Offer letter / contract negotiations, on-the-job counseling, severance negotiations, non-compete and IP issues, whistleblower retaliation & litigation.

37 years | 5,000 cases

50%
Arbitration 20%

FINRA, JAMS and AAA arbitrations are more common now that most employers require employees to consent to adjudicate employment disputes in confidential arbitration forums. We regularly handle client disputes and look forward to handling litigations.

37 years | 200 cases

20%
Litigation 15%

We negotiate / mediate client matters, and when a fair result cannot be obtained, we litigate cases involving non-competes, trade secrets, bonus and deferred compensation, discrimination and wrongful termination in all courts and arbitration forums.

37 years | 400 cases

15%
Discrimination 10%

We handle discrimination cases asserting gender, national origin, race, skin color, age, religion, familial status, disability, retaliation or sexual orientation. You are protected by City, State and Federal Laws. I was a mediator for the EEOC.

37 years | 500 cases

10%
Expungement 5%

We routinely handle the negotiation of U-5s, and we file FINRA Arbitrations to expunge a negative, defamatory, incomplete or false U-5 filing. The U-5 is a minefield, often branding employees as bad actors, impairing one's re-employment prospects.

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.

Incredibly User Friendly

Jonathan is truly one of the best. When I reached out to him for advice not only did he take the call quickly, but he did also so in a way that was thoughtful and comprehensive. He helped my partner and me think through the specifics of the situation and laid out what he believed to be the best pat...h forward. He's extremely knowledgeable and fair and isn't going to sign up for something where he doesn't think he can bring value. I appreciate that about him and while I hope we never need him again, if an issue were to arise, he is our first call and if I were you, I'm make him my first call.

My Trusted Advisor

An incredible mind and top subject matter expert. A quick read and study. Focused on doing the right thing for his clients at all times, regardless of time of day. Built up trust in an instant, was my guiding light at my darkest moment and kept me grounded and focused. No question was a hard ques...tion. I will forever be grateful for Jonathan and his team. This world needs more people like Jonathan...what a wonderful world it will be.

Posted by anonymous | September 22, 2022 | Divorce & Separation

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.

Professional and genuine

I sought Jonathan's representation when my employer let me go after years of discrimination. He was professional, persistent, and genuinely cared about my situation. He quickly negotiated a severance package more than four times what was initially offered to me. I would certainly recommend him.

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
