Questions about this role
Set out in writing what they may and may not advise, train on referring members to a doctor, and discuss any breach. Confirm professional and legal limits with your adviser.
The teaching form differs, with breathing, alignment and small groups, but the same ladder works. Use the discipline's own safety and form examples.
Use the same measures scaled to hours worked, and observe a session. Do not set the same sales expectations as for full-time staff.
