An interesting radio debate the other day which I thought might be worth continuing on STW.
So, it would appear to be a generalisation in the UK that employees consider/feel they have to working some amount of "free" time, or time not dictated by their contracts in order to fulfil career advancement, a raise or the respect of their peers and/or managers.
One side of the argument states that as such we are giving our precious time which could be spent with our families and on our hobbies to the higher echelons who actually do not always work in the same ratio of time worked vs take home pay/benefits. Why then would you work a free hour to line someone else's pocket?
In addition, there is possibly a negative perception on those that do work to contracted hours - the typical comment such as "half day then?" or promotion of one employee perceived to be working longer than another.
Certainly as we grow up and have families out time becomes more valuable to us but equally although money is not the answer to everything, more of it can help life be more pleasant in some circumstances.
