“INNOVATION. LEARNING. FLEXIBILITY. CAMARADERIE. HONESTY. INTEGRITY. COLLABORATION. RESPECT. GREAT PEOPLE. AWESOME BENEFITS. GROWTH. STRESSFUL INDUSTRY…RELAXED COMPANY.”
These are just some of the words employees use to describe what makes Tresys a great place to work. With an 87% retention rate as proof, we think we have developed the ideal ‘recipe’ for creating a flourishing business AND a unique, enviable culture.
We start by hiring innovative ‘thinkers’—58% of whom are employee referrals—who embrace our culture, desire a rich quality of life at work and at home, and hold our core values in esteem. We then add an approachable, transparent management team who truly listens to the staff and customers. Next, we blend in mentoring and training programs designed to identify and provide opportunities for career pathing. We then fold in generous amounts of benefits that include low-cost employee and family medical, vision, dental, and prescription plans with 100% company paid annual family deductibles; substantial tuition reimbursement; corporate 401(k) contribution regardless of amount of employee participation; annual profitability bonuses (historically 8-10% of base salary); and a minimum of three weeks’ vacation. Throughout the year, we drop in events like a family company picnic, our fall anniversary celebration, and the annual holiday bash for employees. We top all of that with a sprinkle of casual environment and a dollop of flexible work hours /schedules to round out our organizational ‘recipe’, ending up with a ‘feast’ our employees find almost irresistible.
