Then why do they keep signing RDW agreements with the TOCs instead of recruiting to full strength?
I do not believe you understand what a rest day agreement is, what it does, and what it gets used for.
I think you misunderstood my comment, I'm not blaming them at all just saying that they ARE usually blamed
I don't think there is misunderstanding. Your comment directly blames them
it's the drivers refusing to work RDs and OT who are to blame,
What you could have said is "Drivers refusing rest day working often get blamed" The problem is always, as that now notorious Tweet from Grant Shapps shows. Rest days are voluntary, they are there to help protect against fatigue, they are contractual, they are a basic employment right, and *slavery died out years ago. You cannot blame someone for not working extra of in their personal time.
Except for those TOCs where the union reps write the rosters, and thus influence the amount of resource required.
Again, there is a misunderstanding here. This isn't the whole truth to what is happening.
Lets take my TOC as an example. There is a fixed calculation for the establishment level. This doesn't change, hence the term 'fixed' What you do is calculate the establishment level and then start building the roster. Again, the roster is broken down into specific calculations of how many 'SPare' turns there are and how many rest days there are. All these are fixed by the Drivers contract.
It doesn't matter who "writes" the roster. The end result is already pre determined. The reality is that rosters will get 'agreed' Reps and **Management will work together to agree diagrams and base rosters. This is actually a very good thing as its a positive working relationship between Union and TOC. It's also a very good psychological tactic employed by the TOCs. Because the Union does the roster, blame can be shifted to them. We have turns that pass to another depot, bring out a unit, drive about all day, then drop the unit back to the depot, and then we pass back. This isn't efficient but because the Union helps and works with the roster clerks, we can kick that diagram to the other depot. The Union doesn't create the Diagrams; Train Planning does.
Just because the Union may be "writing" the roster, doesn't mean they are determining the resources. What may happen, but generally doesn't. Is that there is conflict between TOC/Union. That Diagram mentioned above needs to be kicked back but the TOC will often dig in because of these fixed calculations that exist. The depot can't have that diagram because it would push their ATL (Average Turn Length) over their limit so we get a really stupid, inefficient diagram and it destroys productivity. It's good when there is a decent working relationship between TOC/Union because these inefficiencies tend to get addressed but there is always going to be a need to ensure that the roster and its diagrams are 'legal'
Not forgetting that after the roster gets created, it then goes to Health and Safety reps to check for fatigue index issues.
As I've said on numerous occasions. Rostering is broken, horribly inefficient, and not productive. To blame people for not working overtime is somewhere between laughable, ignorant, and outright offensive. To highlight how inefficient rostering is... Even during the height of COVID with barely a service to mention, we still used ***RDW to cover work. Even now you still get days where you can have SPare Drivers sitting around and someone working a rest day.
*yes , modern slavery exists.
**typically a roster clerk
