Always make sure you're drinking plenty of water during your Stint - we recommend at least one glass for every two hours you work. Also make sure you have eaten food before you arrive.
If you feel very unwell and think you may need to leave your Stint, please let the manager know and our Support Team before you leave. This way, we'll know you had a valid reason for leaving early and we'll be able to assign your Stint to another student who is looking for work.
