My advice would be to develop regular communications to employees using whatever communications channels fit your company's culture. The smaller the organization, the easier it is to check in and evaluate whether employees feel valued. The larger the organization, the more challenging it becomes. But, don't let anything stop you from moving forward. A first step is always a positive step and you can get valuable feedback from your employees if you end the message by asking if the information presented was valuable to them and their roles in the company. You can also poll employees with this question as well to learn if they'd also like to engage in team building events, community service projects or town hall-style meetings. Hang in there and remember to take the first step and ask / engage your employees every step of the way.
