No — if you start your turn with no Workers on your Player Board your entire turn is spent returning any one Worker from the Main Board to your Player Board and you may not place it until your next turn; the returned Worker cannot be taken from the Guildhall, Black Market, Prison, or another player's Board (page 6).

Yes — you may capture your own Workers; captured opposing Workers are placed on the top-left of your Player Board (your own captured Workers return to your supply), and later you can send captured Workers to Prison to gain 1 Silver per Worker (page 11).

You may place Silver on the left-most Apprentice card to skip it (placing always starts on the left-most card and proceeds right if skipping more), and any Silver placed on an Apprentice is collected by the player who later hires that Apprentice; note hiring normally costs a total of 4 Silver (2 of which are Tax) (pages 9–10).

A reset is triggered when all three Black Market spaces are filled or when a Worker is placed in certain left-most Guildhall spaces; after resolving the triggering action, move all Black Market Workers to Prison, flip the top Small Market card onto the Large Market, resolve any Black Market-Reset apprentices, players with 3+ Prison Workers lose 1 Virtue, and the player(s) with the most Prison Workers each take an unpaid Debt card (page 17).

No — once a player has 10 or more Virtue they can no longer place Workers in the Black Market; dropping below 10 removes that restriction (page 16).

Apprentices are not discarded when used to meet skill requirements; immediate effects are resolved as soon as the Building is constructed, while end-game effects are scored during final scoring (page 14).
