That’s a recipe for burnout.
Rather than wait for it, try to prevent it with these steps:
Hold a “recharge your batteries” contest. Ask your staff to suggest ways they would like to revitalize their jobs. Examples might include cross-training or making their schedules more flexible. Try to at least partially accommodate their ideas—and give an award to whoever comes up with the most creative proposal.
Inject fun at work. Host quickie celebrations, such as spontaneous pizza parties. Go around the room and let everyone tell a joke, give a movie review or discuss a hobby. Ask employees to bring in a childhood photo album or box game. When tensions mount, call a “recreation break” and exchange photos or play Twister.
Release pressure points. Nip festering problems in the bud. Intervene at the first sign that employees are buckling under pressure. Example: If the bickering of two cubicle-mates starts heading toward a blowup, separate or reassign them.
