The people in charge of the company do not care about employees.
The hours are not flexible and unless they are regulars the customers are rude. The particular establishment I worked they invested £300,000+ into doing it up to be more trendy but also lowered the overall budget, we recently had a team meeting where the assistant manager complained about overspending on labour and how there is no space for additional staff yet there are only 2 full-time bartenders to deal with the 100+ people per weekend and yet there are 3 minors working as food runners in addition to the 5+ floor staff. In addition to being understaffed, the wage is low and the hours are obscenely long per week (upwards of 40hr/week). in addition to the "optional" shifts that need to be covered and the fact you can only be guaranteed 1 day off per week if that.
DON'T waste your time working for them as you will be tired and miserable from being overworked for peanuts.
Bad management, bad pay, Long hours
