for those with about 60K annual income, approx 5 yrs working experience, how many hours do you put in a day? Do you get to knock off on time or have to work under tight deadlines/overtime most of the time?

My friend's friend earns 4K a mth as a poly lecturer, i think she will get about 2.5mths bonus on the average which gives her approx 58K per annum. She gets to knock off on time (no later than 7pm) except for some days when there are school meetings.

just a 2K difference and I work on average until 8-9pm everyday and high work stress. Not sure if it's worth it, thinking of caving in and taking life easy.
