you do not understand where the poor of motivation on your team comes from?
have you asked yourself these three questions?

they will help you identify the issues.
which, in return, will help you find ways to engage your team.

1. do I communicate clearly with my team?
because insufficient guidelines or feedback make people unsure of what the expectations are, what they do well, and what they need to work on.

solution: audit your communication style to understand how much clarity you provide

2. how psychologically safe is the environment you provide?
because people want to feel that their contribution is valuable, that they are being heard and recognized, and that they can share their concerns.

solution: focus on building trust between all the team members

3. do you support career growth on your team?
because when people feel stuck in a position or when it doesn’t tap into their potential, they do not see the point of doing their best.

solution: uncover the strengths and aspirations of each team member and create individual development plans

because people’s motivation and engagement come from how you treat them.
not from the activities that you think you are engaging them in.
a fruit Monday will never replace your care and interest in them.

as you can see, you do not need to go out of your way, to come up with initiatives.
the answer what to do, lies within your team.
