When it comes to managing a team or undertaking a project, it is essential to stay in control of the situation to avoid chaos. One way of doing so is to keep a tight rein on things, which means exercising strict supervision and control. However, there might be times when you want to loosen up a bit and relinquish some control. In such cases, employing antonyms of 'keeping a tight rein on' may prove beneficial. Some of these antonyms include 'letting go,' 'relaxing control,' 'giving free reign,' 'allowing autonomy', and 'fostering independence.' By incorporating these antonyms, you can create an environment of trust and empowerment that encourages individuals to take ownership of their roles and responsibilities.
