PLANS & PRICING
The ability to make realistic time and output estimations is really an art and something honed over time. If your entire team does the same function (tech teams etc), then your supervisor would be able to make a reasonable estimation of how much time a certain action should take. They might be calculating based on how much time they take, and if you don’t have the level of seniority, there would be a mismatch. Try to send them a regular update on your progress with prior notice if you need more time.
However if you are in an interdisciplinary team, the person doing the estimation might have a realistic understanding of time required for delivery. Part of your job would be to extract a clear brief of what outputs they expect and make them aware of the time required to deliver. It might take time, but it is important to find a balance that allows you to function at your optimum level of productivity - which is in the best interest of the organisation.
Acknowledge the emotions this raises in you privately (journal or with people close to you) so that it isn’t brought into the conversation.
