I quite agree - and I thought they'd shelved the privatisation plans. Passport services should not be in the hands of a private company. And one of the jobs of the manager - really any employee - is to stand up to their boss and say, "I'm sorry but I cannot do that with the resources provided." And then tender a resignation if necessary.
Umm... no. You have a single point of failure, not necessarily a bottleneck.
Again, not necessarily. Insufficient capacity is the bottleneck, no matter the number of sites.
No, it doesn't, but it is a manager's job to ensure the presence of sufficient resources (be that staff, printing facilities, whatever) for the task at hand, and if there are not sufficient resources, then the managers have not been doing their jobs. They get the big bucks; they bear the responsibility. The minister bears the ultimate responsibility, of course, which is why I said that she should be grateful there's just been a reshuffle, so she can't be blamed.
