The frequency of morale-boosting activities will vary depending on the company and its employees. However, it is generally recommended to implement these activities on a regular basis to maintain high morale. Monthly or quarterly recognition and rewards programs can be effective in keeping employees motivated and engaged. Additionally, providing meaningful feedback should be done consistently throughout the year to ensure employees feel valued and supported. It is important to remember that morale-boosting activities should not be seen as a one-time event, but rather as an ongoing effort to create a positive work environment.
