Instagram is the perfect platform for you to share the fun that takes place behind the scenes as well. Since you have chosen to integrate images of your employees, add some images of what takes place behind the scenes as well.
Post images of mistakes that are made, fun times which are had in the office or other fun and play that goes on behind the scenes. No matter where you work, it is not work all the time; there has to be a little fun in any work setting to offset the difficulties of the work being performed. Instagram is a great place to post these images and to show your followers you are a company that does focus on the work and end product, but also knows how to let your employees have fun when they are doing their work as well.
By posting these images, it shows you have a human side as well and allows you to connect to your followers on a human level. Since you are most likely never going to see or speak to your followers, it allows them to see a face behind your name and allows them to see there is a caring and fun human behind all of the work that is being done within your organization.
It shows that your company does not only care about work, but also cares about having fun, about your employees' happiness and about delivering the best product to the client without taking things too seriously all of the time. Just because you are at work, does not mean you can't enjoy what you are doing or what you are delivering to your customers. By posting these fun images and the hijinks that take place behind closed doors, you can show this to your followers and anyone who sees the photos that are posted on your Instagram page.
Your business should not be all work and no play. Make sure you show this to your followers and let them see some of the fun times your employees do have at work. It will make them feel more connected to your business.
