This is essentially a facilitation committee with no fixed roles. Rather than a leader and a treasurer and a secretary, the committee itself has full access to and collective responsibility for council facilitation, though volunteers to take a leading role on different tasks is encouraged.
The financial aspects should mostly be regarding the continued use of a meeting space and associated costs for as long as is applicable, as well as providing members a steady point of contact for their own financial matters, such that any committee member is able to direct members to needed financial assistance both for personal endeavors and for council projects. Members may also of course approach the elected leaders of the Mutual Aid, Community Org and Co-ops Delegation (MACoCo or CocoMA) for those matters as that delegation grows.
While having delegation leaders serve as executive committee members might be tempting, it’s recommended that people try not to wear too many hats so that they can remain responsive in their position. This also ensures that more people are able to have roles at each meeting, as Worker-Tenant Councils are owned and operated by the membership.
That said, it is recommended to have as many delegations represented on the executive committee as possible, and your council may find it to be good practice to elect at least one member of each delegation to this committee, as most council committees and even organizations may also find.
This aspect makes sense, as the Worker-Tenant Council model is designed to be self-replicating at all scales, in the same way that currently, capitalism self-replicates itself at all scales, as a feedback loop. Our feedback loop is the delegation structure, so it is no mistake that anything formed by or associated with the Worker-Tenant Councils will resemble them over time.
