How We’re Handling Covid-19

We are extremely grateful to continue to grow as a company during these unprecedented times. Our #1 priority is the health, safety, and wellbeing of our current and future R3’ers. We want to share with you what we’re doing and what you can expect throughout our interview and on-boarding processes.

Since March, most R3’ers have been working remotely, although we have opened some key office locations global, with limited capacity for those that cannot work from home or need to come into the office.

As you go through the virtual interview process with us, please don’t worry if children or pets make a guest appearance. We understand these things happen- it’s real life after all! If we are fortunate enough to welcome you to the team, we’ll get a laptop couriered to you and get you set up virtually on your first day.  We also provide you with a “Work From Home” allowance to enable you to purchase some equipment to be more comfortable and productive.

We Have And Will Continue To Take Steps To Ease Some Of The Burden For Our R3’ers

We understand that Work From Home (WFH) life can be challenging in many ways, so some of the additional support measures we have in place include;

  • New Starter WFH allowance (as mentioned above) to get you setup to work productively at home
  • Additional access to wellbeing resources (as well as the support provided as part of your Vitality Private Medical) including a year’s free subscription to the Headspace app and modules on our Lessonly training platform from MindGym (including Goal getting, Stress Busters and Virtual Work)
  • We also have additional health and wellbeing resources available on our wiki pages when you join.
