There are plenty of words and phrases that can be used instead of "morale building." If you're looking for a more formal term, "team cohesion" or "team-building exercises" may work well to describe activities that help to boost camaraderie and motivation. "Employee engagement initiatives" is another term that can be used in the context of creating a positive work environment. Similarly, "motivational activities," "inspirational talks," and "pep rallies" can all be used to spark enthusiasm and create a sense of unity in the workplace. Whatever term you use, it's clear that keeping up morale is an essential part of building a successful team.
