Work Reassignments When Staff Leave

Determining who to reassign work to can be challenging when there's no replacement, or when the replacement ends up doing somewhat different work.

A further complication is that we prefer to not have unassigned work items (that aren't on the "wish list").

Leaving them assigned until a replacement staff member is found can result in a lot of inappropriate email to the departed staff member.

One step that is usually safe, and can be mostly automated, is to remove the departed member as a "helper" on work items. A "helper" is someone who's not the lead for the work, and it's sometimes the case that they're listed simply to receive email updates.

The general approach to this is to use the `st-qlist` command to discover all open items with the staff member as a helper, check and edit the result into a form suitable for the `st-set-field` command and then use that command to make the change. That has the advantage that it can be done in bulk, and it doesn't send email to all the other owners about the change.

E.g. edit the result of st-qlist -f +owner,responsible "owner like '_%USERID%'" into a form suitable for the `st-set-field` command and then use that command to make the change, trying it first with the -n option to check what changes will be made. "responsible" is included in the st-qlist output as it might influence the choice of who the owners are to be.
