As previously stated, subway will not hire minors under the age of fifteen.
Can you be 14 and work at subway. Check the laws in your area though, but in england. Well i am 14 and i have a job at subway honestly it depends on the manager. In most states, the general minimum age for subway employees is 16.
Most places you cant legally work at until you're 16; Subway hires no one younger than 15, and minors, like other. No you must be 18 or older.
In most cases, however, subway will only accept job applications from people over the age of sixteen. Or even 18 in some cases.
