At my
venue we don't actually have any official dress code as such. We have a
safety code regarding footwear - boots with reinforced toes* if you're working onstage or in any of the construction areas (however the flymen get away with sneakers on showcalls if they don't come down to
stage level) - and an official policy about wearing hi-vis vests in the loading docks, but nothing specific about clothing. We don't have nametags, however everyone carries their
venue photo ID with them (it's our access card to all lifts and doors), though very few production staff actually wear them openly - most of us just carry them in our pocket so they don't get lost or snagged on things. We do have basic guidelines for attire for certain show conditions:
"Full Blacks" - black pants or jeans, long-sleeved plain black shirts, black boots. Common for ballet, or any show with a high chance of being seen. We'll add gloves and balaclavas when required for ninja cues.
"Dress Blacks" - black pants (preferably slacks), long-sleeved button-up shirts, black boots. Common for live changes during orchestral gigs, or any other show where we need to present an especially smart appearance.
"Show Blacks" - black pants, black t-shirt with minimal print, black boots. Most staff tend to wear crew shirts from previous jobs, or the t-shirts given out by the
venue - we get a couple of t-shirts when we start, a production shirt each year, and other events often have crew shirts, so everyone has plenty to choose from. The
logo shirts are not a uniform as such, but on big gigs or with new clients it's useful for the client to be able to see who is in-house crew and who is touring/local hire. We also have a couple of unofficial crew shirts printed by one of the staff who has his own t-shirt business - they're popular with our resident companies as well. Only on certain gigs will we be specifically told to wear venue-logo shirts, and on some very sensitive gigs we'll actually have to display our IDs (eg: Oprah required
logo show blacks, the APEC summit required visible ID and specific security passes in sight at all times - the diplomatic security guys were rather twitchy...), but the rest of the time its just common sense, and as long as the print on your shirt isn't outright offensive or inappropriate, you're good to go.
For general work calls we don't really have a guideline apart from the boot rule - most of us wear our grungiest work gear for in/out and
build calls. Shorts are fine on non-showcalls, or if you're working outside - though you're risking sunburn in summer, so most of us opt for long pants outside regardless. The
venue has a
stock of t-shirts, button-up shirts, cargo pants and boots - so nobody is ever sent home for not having the right thing to wear, they're just sent down to the office to get kitted out (usually happens when someone gets moved to showcall at short notice and doesn't have the right gear with them).
*not necessarily
safety toes - the ones provided by the
venue are Redback brand with plastic reinforced toes, but we can buy our own and as long as they meet the
safety standard the
venue will reimburse up to $80 of the cost. Most of us who buy our own get steel or composite toe boots anyway.
