What should "Work" do? (Patreon)

We are in the gameplay phase currently, I am brainstorming a lot and trying to make the gameplay good. I would like your guy's opinion on this on what "Work" should do. (Work isn't going to be 1 button click, there will be multiple options for it.)

1. Instant work like HFGR1

2. Non-instant work, you click the button and employee will work for 5 to 120 seconds (depending on what task they are doing) until they are available for more work.

3. Assign 1 specific task for the employee to do. They will keep doing this task until you change it. (Automatic working)

4. Assign multiple tasks for the employee to do. They will keep doing these tasks until you change them. (Automatic working)

5. Do both 1. and 2. - Make 1. cost more energy to do since it is instant. (you can decide if you want to instant work them, or put them on a work timer.)

6. Do both 1. and 2. and 3. - Make 1. cost more energy to do since it is instant. (You can decide whichever way to work them.)

7. I don't like all the above. Think of something else for gameplay.
