After 3 years there, what seems most unfortunate is the contradiction that LHH's impact on other businesses is wholly positive. Colleagues at client organisations are positively impacted by LHH no doubt.
Employees at LHH however... Most quickly realise they should use LHH as a stepping stone, get some new experience, try to enjoy it along the way, try to avoid the office politics and power plays, ignore the poor pay and good colleagues leaving consistently...
Just create a positive story for your own career and move somewhere where employees are valued. If you care about your work environment and want to take pride from the culture you are part of, then your time is much better spent somewhere else.
No-one cares about the business out of choice, because it would be too difficult to improve and the few colleagues in leadership who are benefiting from the status quo would block efforts for positive change anyway. They would rather sit doing sub-par work and eventually move into retirement.
It seems they believe it cheaper to 'get out of LHH colleagues what they can' while they are LHH employees, because there will always be enough prospective hires who find the idea of LHH as attractive. If you look at where the money is spent, it's not spent on creating sustainable business practice it's spent on short term fixes and just doing enough to keep key clients.
At LHH you will work hard because you have to.
If you want to work hard because you choose to, because you enjoy being part of something larger, then just don't join LHH in the first place.
I was hesitant to write an honest review because there are a few great people, the CEO of UK/IR for example JC, and the career transition coaches who do an amazing job of impacting peoples lives. But for the vast majority of colleagues they will just find themselves an example of what they do NOT want from their own career.
