As much as remote work can be fraught with challenges, there are also relatively quick and inexpensive things that managers can do to ease the transition. Actions that you can take today include:
Establish structured daily check-ins: Many successful remote managers establish a daily call with their remote employees. This could take the form of a series of one-on-one calls, if your employees work more independently from each other, or a team call, if their work is highly collaborative. The important feature is that the calls are regular and predictable, and that they are a forum in which employees know that they can consult with you, and that their concerns and questions will be heard.
Provide several different communication technology options: Email alone is insufficient. Remote workers benefit from having a “richer” technology, such as video conferencing, that gives participants many of the visual cues that they would have if they were face-to-face. Video conferencing has many advantages, especially for smaller groups: Visual cues allow for increased “mutual knowledge” about coworkers and also help reduce the sense of isolation among teams. Video is also particularly useful for complex or sensitive conversations, as it feels more personal than written or audio-only communication.
There are other circumstances when quick collaboration is more important than visual detail. For these situations, provide mobile-enabled individual messaging functionality (like Slack, Zoom, Microsoft Teams, etc.) which can be used for simpler, less formal conversations, as well as time-sensitive
