In theatre, we're all self-starters. Promptness and Respect for Deadlines Tardiness is never acceptable in theatre because it shows a lack of self-discipline, and more importantly, a lack of consideration for others. Being late for a rehearsal or a work call or failing to finish an assigned task on time damages a production and adversely affects the work of many other people. Theatre demands that you learn to arrive on time and meet scheduled deadlines. That's a job-skill.
Employers appreciate workers who are on time and do their work as scheduled.
In theatre you work within the structure of a set of procedures and rules that deal with everything from shop safety to behavior at auditions, rehearsals and work calls. Theatre teaches you the importance of rules, a concept that's valued in any organization. Your work in college theatre will show that you have the ability to grasp complex matters in a short period of time, a highly-valued trait to employers. If you don't listen, you're likely to make some major error that will damage the production. Listening is a skill for any job.
