I'm not going to tell the committee how to carry out its business. What I can tell you is that there are rules that already exist around public servants needing to disclose whether they have other employment income sources. That disclosure is meant to ensure that there isn't a conflict of interest between the duties of a public servant and other duties that they may have.
I would argue that it's a situation in which the rules need to be enforced. It starts with awareness, making sure all public servants are aware that the rules exist, that the disclosure happens, and that the dialogue happens between a supervisor and an individual. Then, finally, once a decision is made as to whether other employment is allowed or not, it's well documented so that there are no situations of ambiguity, so that it is very clear that a public servant should not do something that would impede their ability to be objective and fair as they carry out their responsibilities.
