This will probably end up as a case study in how not to do change management.
Assuming that this is a good idea (I don't know what the science says,) then forcing a rule on the workforce should have been a last-ditch effort. Engaging the workforce more collaboratively would have been a good start.
Assuming that a rule needed to be imposed because the science was clear and all other attempts at creating the change failed:
If the rule was "everyone must get the vaccine" or "everyone must wear a mask" then it would be possible to enforce. However, with this hybrid option, workers can easily choose to not get the vaccine and not wear a mask. Unless they have to walk around in different coloured uniforms, who is really going to keep track of who is vaccinated or not? It doesn't sound like the rule has the support of health workers so they aren't going to tell on eachother. Patients are the only people who might actually raise concerns but there will be no way for them to know who is vaccinated or not.
It's always a bad idea to introduce a rule that will often be broken and rarely enforced.
At the end of the day, we need to provide health workers with the right resources and training and then trust them to take their responsibility seriously and do their job well.
The message from the provincial health officer is disconcerting. It is his opinion that we can't trust health workers to protect patients from the flu. If that is the case, does he have any confidence in their ability to prevent the transmission of much more serious infections in health care settings?
