Officers must be re posted every three years says customs boss

It sounds like you're referring to a statement made by a customs boss regarding the rotation of officers. According to the statement, officers must be reposted every three years. This means that they will be transferred to a different location or role within the customs agency every three years.

This practice is likely in place to ensure that officers receive regular breaks and opportunities for professional development, as well as to prevent burnout and stagnation. It also allows the agency to rotate in fresh perspectives and skills, which can help to maintain efficiency and effectiveness.

It's worth noting that this is just a general guideline, and the specifics of the reposting process may vary depending on the customs agency and the individual officer's circumstances.
