Pros
Quick progression to senior administrator in administrative roles, decent winter and summer bonus scheme, employee of the quarter award (with payout bonus), the company will offer to pay for further qualifications, good opportunities for starter jobs/step up jobs, dress casual and no formal attire required, leave early on fridays, paid overtime, modern offices to work in, always food and treats each week, easy to familiarise yourself with people in other departments and get to know everyone in the company.
Cons
High turnover of staff, low wage for administrative staff, managerial staff untrained to manage properly, lack of transparency with communication, will prohibit progression if the company want to, social life is minimal, some line managers will not back you for pay rise or promotion, HR sometimes unhelpful and things said to HR are not always confidential, staff can be very "cliquey", huge amount of favouritism and rules can change according to the department or how managers feel about a person, micromanagement is excessive and managers have a playground mentality. When things go wrong they are highlighted and there is a mentality of allocating blame and publicly shaming, employee of the quarter is a popularity contest and mostly rigged, lack of flexibility.
