Before you have to do one of those "Re-Commitment" apology commercials or messages like Wells Fargo, Facebook, or Uber, re-examine your culture and the way you do business.
Use technology to engage and enhance the human connection with employees rather than simply implementing technology under the illusion of being a technologically advance organization.
Look beyond surface-level problems in your culture. If your team has been in a state of discontent for months, the problems probably stem from a point much farther in the past.
