Social Day – One paid day per year to give back to your community or support a cause you care about. Extra sick days, no questions asked – Get 2 paid sick days per year, no doctor’s note needed.

Pick your perk – Choose what works for you via the Benefit Online platform: private pension, meal tickets, travel vouchers, courses, gifts - you name it. Work-from-home allowance – Whether you're at your desk or at home, we've got you covered. The allowance adjusts based on your time in the office. Hybrid work is a natural part of how we operate, but we also believe in the power of coming together.
