That's a great question! No, there is not a minimum number of shifts you have to work after signing up and being approved by ESHYFT.
At ESHYFT, you have complete flexibility - you can choose when and where you work. Some ESHYFT employees choose to be full-time, others are part-time, some are seasonal or sporadic.
If you do want an ESHYFT badge, you do need to work at least one shift. To learn more about badges, please read "When will I receive my ESHYFT badge?"
