However, what we are constantly striving to accomplish at MJ is that the ESOP is much more than a benefit, it is our culture!

Here at MJ, we positively impact peoples’ lives every day. Whether redesigning a highway interchange to improve safety, renovating a building to improve comfort and energy efficiency, or implementing an in-house training seminar that allows our staff to grow personally and professionally, we take on the opportunity to make a difference passionately.

Every project we undertake has unlimited potential for innovations that can add value for our clients, the users, our environment, our employee-owners and our communities.

Our business philosophy has always relied heavily on teamwork, and we believe our employees should share in Tata & Howard’s success in an appreciable way. That’s why we created a 100% ESOP, which went into effect in October of 2014. An ESOP is a type of employee retirement benefit plan, where employees become shareholders in the company. Similar in some ways to a profit-sharing plan, an ESOP rewards employee-owners relative to the financial success of the company. In this way, employee-owners are accorded a real ownership stake in the company, and are therefore driven to work both harder and smarter for the company. Since its inception, Tata & Howard’s values have included both integrity and teamwork, and adopting a 100% ESOP has contributed greatly to those values. Our team members strive to improve efficiency and innovation while consistently maintaining a strong sense of responsibility for the wellbeing of both the company and each other.
