There are a couple of issues. I do not think the code above will work as you intend. The SidekiqWork is run asynchronously with the rest of the code. It looks like your code might be subject to a race condition. You cannot control if the worker code runs before or after the gmail.logout() call.

In addition, it's generally not considered a best practice to pass an object as an argument to a Sidekiq job. See the Sidekiq Best Practices. Instead, I might consider making the gmail connection from within the Sidekiq job.

As an alternative, you might consider using a class method in a lib class that stores an instance of the gmail client. You can memoize this connection like the following:

 class GmailClient
   def self.connection
     @client ||= Gmail.connect("[email protected]", "password")
   end
 end
