Please help me understand the famous wage gap difference [View all]

"women working full-time earned 77 cents for every dollar earned by men working full time" - This is a famous line used by many people addressing wage gap. I know that this study was done by BLS but i want to know if they considered following points


1) Does this report consider that full time men work 8.5 hours instead of 7.9 hours (for full time women). I am just talking about full time workers (35 hours per week or more).

Source (BLS - 2013 Report) - http://www.bls.gov/news.release/atus.nr0.htm

Thus, a daily 0.6 hours more work translate to 3 hours per week more work.

2) Does this report take other worker's benefits into the consideration (like vacation, sick pay, maternity leave etc)?

3) Does this report consider the scenario where workers opted for a low paying job for exchanging the benefits like low commute time, flexible work hours etc?

4) Does this report consider the scenario where workers opted for harsh-working hours (like night -shift, weekend shifts) in exchange of more wage?

5) Does this report consider the percentage of men/women doing overtime work? Also specifically does this report consider how many average hour of overtime is done by men and women? (Overtime usually starts from 41st hour of the week)
