i loved my job and i wish i hadn't hadnt left. all my shifts fitted around my personal life. for making sandwiches, its actually very well paid and so much fun!
there is a pension, paid holiday all sorts. i really loved my job. the only downfall is a zero hour contract. this was also the biggest attraction.
however, they are all franchises, so it depends on your individual employer and colleagues.
free food, food discount, massively flexible hours
unreliable hours, although always able to pick up extra shifts
