If that is your question about working for Showsec, I think this may not be the job for you. Staff searches depends on the venue and event. Turnover of staff is high and numbers of staff working means it is impossible for every supervisor or Ops manager to know each staff member enough for personal trust. Members of staff and the public should both be expected to be searched and have nothing to hide to keep venues, events and each other safe.
Yes cos they don't trust the own staff they really don't
Why do you ask
No as lockers are provided. For football evens where lockers cannot be provided - then yes they search you
