I have slightly more time (I'm almost ready for bed), but the only rulebook I can find dates from 2008. I have no idea which rulebook is appropriate from this page (
http://actorsequity.org/library/library.asp?cat=3), but this book (
http://actorsequity.org/docs/rulebooks/LORT_Rulebook_05-08.pdf) states:
Rule 63. STAGE MANAGERS AND ASSISTANT STAGE MANAGERS
(B) Assistant Stage Managers. (1) An Assistant Stage Manager is the individual who is assigned to assist the Stage
Manager(s) on a specific production or productions. An Assistant Stage Manager may
not be assigned the primary responsibility for a production. No Actor already under
contract may be assigned as Assistant Stage Manager in the same production. The
first Assistant Stage Manager may not act.
(2) In all Theatre categories, each required Assistant Stage Manager shall be engaged
and receive contractual salary beginning at least two days prior to the first day of
rehearsal for each production of the season unless already under contract.
(3) A replacement Assistant Stage Manager may be engaged on a one-week contract.
(4) “A” Category. There shall be at least one first Assistant Stage Manager in each
company, and in addition to the Stage Manager, each production must be assigned an
Assistant Stage Manager who shall be responsible for and perform the Assistant
Stage Managerial functions. If an “A” Theatre performs in Repertory, at least two first
Assistant Stage Managers must be employed.
(5) “B+” and “B” Categories. In addition to the Stage Manager, there shall be at least
one first Assistant Stage Manager in each company. Each production must be
assigned an Assistant Stage Manager who shall be responsible for and perform the
assistant stage managerial functions. When more than one production is in rehearsal
and/or performance, the stage managerial staff shall be, at the Theatre’s option, either
two Stage Managers or one Stage Manager and two Assistant Stage Managers. If the
Theatre does not hire a second Assistant Stage Manager, the first Assistant Stage
Manager shall assume the stage managerial duties and shall be contracted by rider as
Stage Manager for that period. Should the Theatre choose the option of two Stage
Managers, each may be assigned as Assistant Stage Manager for the other
production.
(6) “C” Category. In addition to the Stage Manager, each Chorus musical production
must be assigned an Assistant Stage Manager who shall be responsible for and
perform only the Assistant Stage Managerial functions. This provision shall expire
February 28, 2009.
In non-Repertory Companies, when there are individual Stage Managers for each
production, no Assistant Stage Manager shall be required. However, when more than
one production is in rehearsal and/or performance, there shall be, at the Theatre’s
option, either two Stage Managers or one Stage Manager and two Assistant Stage
Managers. If the Theatre does not hire a second Assistant Stage Manager, the first
Assistant Stage Manager shall assume the Stage Managerial duties and shall be
contracted by rider as Stage Manager for that period. If a “C” Theatre is performing in
Repertory, at least two Stage Managers shall be employed.
(7) “D” Category. In addition to the Stage Manager, each Chorus Musical production
must be assigned an Assistant Stage Manager who shall be responsible for and
perform only the Assistant Stage Managerial functions. This provision shall expire
February 28, 2009.
In non-Repertory Companies, when there are individual Stage Managers for each
production, no Assistant Stage Manager shall be required. However, when there is
only one Stage Manager and there is one show in rehearsal and one show in
performance during a given week, an Assistant Stage Manager shall be required. If a
“D” Theatre is performing in Repertory, at least two Stage Managers shall be
employed.
I hope that helps?
