Across the combine, stations-side management structures seem to be backed up when it comes to signing new starters off probation.
Some are blaming ongoing "Fit for the Future" processes for creating backlogs of work. It may well be the case that DSMs and GSMs have had increased workloads as a result of "Fit for the Future", which will, after all, affect their grades too. But new CSAs shouldn't be punished by effectively having their probation informally extended, through no fault of their own.
A six-month probation period is stipulated in the contract. It should only be extended due to serious performance or disciplinary issues, which should be clearly explained. Informal extensions, because management is too busy dealing with other things, are not on.
Of course, the company could scrap "Fit for the Future", an unnecessary and regressive tranche of changes that neither staff nor passengers need, and save themselves - and us - a lot of bother!
