bwayleadman--things have changed I guess because much of that is not how things currently work.
-you pick up an application at the theatre chain's offices (nedelander, jujamcyn, etc.)
-you don't get paid hourly. you get paid for the performance
-as with equity, when you join, you pay an initiation fee. then, you have dues 4 times a year (currently $36.45) and 2% of your pay.
any usher, full time or sub, gets more money if you work on a sunday or a holiday. and vacation is paid every check-a percentage.
ushers can not call other ushers to work for them. at least, this is the way jujamcyn works. the manager call the sub list.
