Sadly, some firms are like this. They like their staff to record an 8 hour day on their timesheet, despite the fact that these staff may in fact (and for the kinds of companies that engage in this practice, probably are) working closer to 15 hour days.If everyone else is putting 8 hours on their timesheet regardless of what they actually work, then my advice would be to go with the flow and do the same. They'll judge you at your appraisal on % of working days billable rather than % of working hours. In these kinds of companies, they just expect you to work long hours. Why they record 8 hours is beyond me... maybe so everything fits nicely into their little accounting system and budget reports or so that they can show the HSE that they aren't engaging in dodgy HR practices?If it's only you and your team that's working silly hours, then you need to make sure you get some recognition for it. If your manager is the sort to speak up for you at appraisal time, then it may be worth doing him a favour. If he's the sort that wouldn't blink an eyelid if he found out that you were being 'counselled out' then I suggest you need to take action, and fast. Get staffed on another project, whine about it to HR, or just ride it out and make sure you don't work with him again in the future.My main advice however would be to remember that slavery has been abolished for a long time now, and an employment contract is a 2-way deal. What are you getting out of it? Do a cost-benefit analysis and look at other options. Don't be afraid to apply to other companies which have a more humane approach to managing their staff - sometimes, the grass really is greener! I worked for a MBB firm for several years and used to dream about working for the client. The pay was almost as good, and they worked half the hours! They were nicer people too (less competitive/pushy). They also didn't have massive job insecurity, unreasonable travel and unrealistic expectations of what their staff are supposed to achieve like the firm I worked for did.Also, in my experience, the 'killer projects' (the ones which are constantly pulling 'all nighters' and so on) are the ones that invariably fail. If the whole firm works this way, why not freshen up your CV and put the wheels in motion for bailing out? Does your firm have an 'up or out' policy? If so, you may do well to beat them to the gate and move on before you're pushed (which, statistically, will be very likely within a few years).Every cloud has a silver lining - and this may be a prompt to get you looking at greener pastures? There's more to life than slaving away in Brussels/Hamburg/whichever faraway boring city you've been staffed at for 85 hours a week in front of PowerPoint for £45k a year, you know!
