Pros
Opportunity to progress in terms of job title and training opportunities are there if you are consistent with presenting a case for it. Flexibility with working hours, again if you present a case. Retailer/gym discounts seem interesting.
Kontras
Revealing your skillsets will lead to more senior work once positive results are realised, but there is no acknowledgement. Tribal mentality leading to colleagues turning an eye to heavy bullying in some offices. You have to do as the populars do, speak how they speak, allow popular senior staff to make inappropriate and even racist comments, and not 'show off' by revealing you have logic or reason while solving simple problems to not become a target for harassment. Full scale personal attacks, digging into peoples private lives and characters, like secondary school bullies who need you to pick sides in matters of rank and gossip. In my opinion HR does not seem to have a thorough understanding of how to manage any issues besides wage slips and holiday. They lack integrity when approaching issues objectively and effectively and struggle with comprehension of individual issues, forcing everything to fit into boxes they are comfortable with, ethically the department needs work. If you believe in allowing people to be themselves and aim for the high instead of mediocre, you have to tread very carefully, people will project their personal issues on to you and make life difficult to make themselves feel better about their shortcomings.
