Your main goal is to create a team of people who all work for the same purpose. No one team member is allowed to work on his or her own. As the manager, hold regular meetings with your employees and remind them that they are working for the common good.
Create a list of collective goals that every individual worker must follow. For instance, create an attendance schedule that everyone must obey to keep the business operations flowing. If some employees show up tardy for work, or do not appear at all, make sure you have other employees on standby. If several of your employees become incompetent, have other workers willing to step in and compensate for these losses.
Also, encourage your employees to act as team members and help each other. An employee who needs more training on a topic should ask a coworker for help instead of the manager. The manager is not always available to give assistance. Sometimes, it is better that the employees take the initiative and figure out their own solutions.
