1. New initiatives instigated in March/April last year as a result of the first set of stats will not yet be embedded - we wont see the results until next year 2. Initiatives aimed at increasing the numbers of women in the workplace often aim to bring more women in at graduate level and train them up - this probably puts them on lower rates initially and increased numbers of women on lower rates increases your pay gap - we probably wont see results for years to come yet 3. Two wrongs dont make a right and companies who are fixing EPA gaps should be focussing on negative gaps (in favour of women) as well as positive ones (in favour of men). Dependent on placement within the structure, this may well drive up the pay gap.
I will be interested to see what happens next year. Its too soon to categorically say there's been no improvement.
