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.

Best in class

Jonathan was great - he helped answer all of my questions about my severance package and offer letter from another firm. He was very responsive and gave me lots of time and attention. I highly recommend him to anyone.

Insightful Advice, and Very Prompt

I asked Jonathan to review my employment agreement. I sent it to him on a Sunday, and he gave an answer in 30 minutes. In our follow up discussion at 9 PM (!) two days later, Jonathan was very thorough. He pointed out a number of flaws in the agreement. Ultimately, he put my mind at ease on the matte...r. It is evident that Jonathan has many years of experience and great insights. I would definitely engage him again and I would highly recommend him to everyone. Bottom line: Jonathan has great experience and knowledge and works 24/7 for clients - what can be better than that!

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.
