I guess that’s what happens when you lower your hiring minimums to zero and are willing to put literally anybody in the seat.
That's just part of the problem.
The other half is this insistence on employing rostering managers who are basically admin clerks. Our ICM manager has no idea about actually living with a roster. All he knows is the 15 or so years he spent as his apprenticeship under the previous incumbent.
That's why we have jumbo crews spending 15 nights a month in the ANC hotel and barely hitting 70 credit hours. Manager ICM honestly believes because you're at work (ie on a company duty away from home) for 21 days, then you're being efficient and productive.
It's not his fault though - the fault squarely lies with the managers who appointed such woefully incapable individual to the position, and even worse, the same managers who've allowed him to remain in that position, despite his very obvious shortcomings.
