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.

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.

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.

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.

Highly recommend: Effective and Highly Efficient

My lawyer was effective and highly efficient throughout the process. One of my biggest fears was having to regularly see the abuser and even a more hostile environment while the case was handled. Prior to Mr Sack’s involvement, individual regularly aggressively screamed at me and intimidated me (6’...4 tall man banging books on the desk while aggressively screaming at me, 5’2 woman, because I enquired about internal opportunities), constant sexist comments on my voice, clothes and personal life, “jokes” about using “mothers room” after returning from maternity leave in front of everyone (toxic trading floor) or email. However, as soon as Mr Sack got involved, the harassment and intimidations almost immediately stopped (that alone was such a relief). Work accommodations were quickly made; I didn’t have to see or hear the individual, except via email and only work-related requests. When it came time to leave, the process was seamless—I left without any awkwardness, confrontation or regret. Most importantly, the matter was resolved with fair compensation. I’m deeply grateful for my lawyer’s professionalism, guidance, and support during such a challenging and hostile situation.

Trusted Advisor

I was referred to Jonathan by a former colleague who also negotiated a settlement with my employer. From the minute that I reached out to his office Jonathan was responsive, helpful and sympathetic. I was initially taken aback by Jonathan's aggressive style but as we worked together we developed a ...good dialogue and rapport. I followed Jonathan's advice and I trusted him to manage the process and he delivered as promised. I have already recommended him to several other colleagues who are in similar situations.

Aggressive Workers' Rights Lawyer

Employers who break the law do anything and everything in their power to delay and avoid paying for their actions. Jonathan keenly understands what it takes to bring a hostile defendant to the table to bring recompense for aggrieved employees.

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. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

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.
