Yes, you can vote to suspend effective Friday if you want and the house also agrees. A captain, or designated rep, from every team needs to vote. Can you get a full vote via email or by calling the team captains and getting an answer? Is suspending league for a few weeks really going to make people feel better? It isn't like everything is going to magically get better in a few weeks...
With Friday being position round, there really isn't much else you can do. You can't really permit post-bowling for a position round (post bowling was the solution here recently for bowlers that were nervous during the increase in cases.)
