22 weeks maternity is true and good, but it does not mean Barcap/Barclays advocate work life balance. In fact the work life culture is quite bad. No one dares to leave early as the boss will feel that he/she is very free and need to be loaded with more work. (In general at least).

Official working hour are 9am - 5 pm. No one dares to leave at 5pm (unless you have tendered). Typically people leave at 8pm when low peak and leave at 11 at peak periods.
