If you base your lobbying on speaking to a few people, you are in for a shock.
I’ve just looked at the members of the ISSG over 2 years. At the service level, there has been over an 80% turnover. At the Cabinet level, it is around a 35% change.
It is a helpful reminder to keep your ear to the ground and engage proactively with the limited group of people working on your file. If you step out for a few months, the people deciding on your issues could look very different.
I suspect the high turnover is linked to burnout from being asked to produce significant legislative changes quickly.
