Ventajas
Absolutely nothing, even the free coffee is the cheapest one they can buy.
Desventajas
Backwards, sexist, stuck in their ways, not willing to change. Will bully staff, management is unprofessional. Report issues to HR and they are brushed under the carpet to protect the manager rather than the employee. Very horrible environment to work in, staff will be nice to your face but happily back stab you to management to make themselves look better. God help you if you are female, there will be limited chances for you and if by chance you do get promoted, they will find a way to pay you less than a male member of staff in the same role. Don't forget the annual slap in the face for all your hard work. A £10 M&S voucher and a mince pie!
