How do you prioritise multiple tickets when everything looks urgent?
I prioritise by impact and urgency, not by who shouted loudest.
First I apply the service level agreement: anything breaching a contracted response or resolution time, or affecting a critical system or many users, comes first. A single user with a cosmetic issue waits behind an outage affecting a whole account.
Then I consider business impact: revenue at risk, safety or compliance, and whether someone is blocked from working. I group similar tickets so one fix resolves several.
I communicate proactively. If a customer will wait, I tell them the expected time and why, which usually reduces anxiety. I use the ticket system to keep statuses accurate so the team has one view, and I flag to my manager when volume exceeds capacity rather than quietly letting service levels slip.
At the end of each day I check that nothing critical is at risk overnight.
