Working remotely can drastically change how and when you can interact with other co-workers. So in your own little way, continue small 'office practices' to help bring your team together. This might include sending funny, work-appropriate GIFs over Slack, text, or email; chatting about sports or your family or anything else you would normally do by the water cooler, and volunteering together through an online charity project instead of an in-person event. Though you must try to keep your conduct aligned with your current company's culture and rules.
IRLDO keeps your remote team accountable and together every day.
