The hours at Towers Perrin are fairly standard for consulting. They vary with client requirements, the project cycle, and line of business (different practices have different degrees of predictability to their project cycles).However, one of the things that makes Towers Perrin a particularly good place to work is that you have a substantial degree of discretion as to how, where and when you work to best serve the client. I find that having the flexibility to work from home, client site, or office depending on the requirements of the day helps a lot with maintaining sanity and work/life balance around the office.Other factors affecting your working hours at Towers Perrin are: your working style; your choices to get involved in business development, intellectual capital generation, training and other internal projects; and your general ambition. There are substantial opportunities for career growth if you wish to take them. However, there isn't a strict "up or out" culture, so not everybody chooses to do so. I find that many people at Towers Perrin are very open about sharing their intellectual capital and (where appropriate) client relationships, and will listen to good ideas. Once you make them aware that you're interested and demonstrate that you're capable, I've been impressed at how far they will go out of their way to involve you in projects and internal initiatives. Naturally, reciprocal behaviour is required.Lateral career mobility is very good, especially given that many people come from specialised backgrounds (actuaries, psychologists, etc.). Having made connections and demonstrated ability on the job to colleagues in different locations and lines of business, a lot of people end up going on secondment or transferring during their time with the firm. For example, I was speaking with somebody the other day who has been with the firm for 10 years but, having been based on three continents in that time, said that he feels like a relatively new joiner. There are also a number of actuaries who trained with the firm but subsequently developed into non-actuarial leadership roles (effectively a change of profession and working style).Upward career mobility can be more difficult to judge than lateral mobility since Towers Perrin is a fairly flat organisation (there are only three consulting titles). However, salary progression and time from entry to partnership (9-13 years approximately) are similar to other firms. In my experience, career development outpaces peers at other firms.Feel free to post here or get in touch directly (firstname.lastname@firmname.com) if you have any other questions. I'd be happy to clarify any of the above in respect of your particular professional background and career level.
