Peruse the Heck outta the Stage Managment forum here. There have been a lot of good discussions about various ways of doing things, different opinions and answers for whatever type of SMing it is,
Theatre is Much different than R&R. R&R is a lot different from Dance. Dance is different from anything in the known Universe.
Organization, keeping a precise, up to date, and clearly understood, script is a requirement under Equity rules for an SM. If you get hit by a bus 10 minutes before the show starts, another SM needs to be able to walk into the booth and call the show. Be Firm but not unreasonable. Respect is better than fear, but I'll settle.
