An "average" pilot has the following type of schedule and pay for a month, using the airline I work for as an example:
Avg Monthly Days worked - about 11
Avg Monthly Hours actually flying - about 55-60 hours
Avg Monthly total paid hours - about 75-80
Avg Monthly Pay - $12,000 ($144,000 annually)
The TAFB is kind of a meaningless figure, as it is only used in calculating their per diem and penalty pay. It is not a representation of "working" because it includes all hours away from home, including when they're sleeping in their hotel room.
The 20-25 hours of monthly pay that are not from flying the aircraft are largely made up of vacation, sick and penalty pay. The penalty portion (about 5 hours per month) is driven by the TAFB, which encourages our schedulers to construct trips that use pilots efficiently, (i.e., doesn't have them sit in a station for a couple days waiting for their next fligth).
In general, you could say that they "work" about 8 hours a day for about 11 days a month, if you include the pre and post flight time they spend on duty that does not get captured in flying pay. Obviously, they're away from their family for those 11 days sleeping in hotels and eating airport food, so quality of life somewhat offsets that relatively low "working" schedule. They are also constrained by FAA limitations on the number of hours they can fly in a month and in any given 24 hour period. There are much more productive pilot groups (Southwest, Jetblue, etc), but I don't know the particulars of their regular schedule. My example is what you'd likely see at any legacy carrier.
Hopefully this helps to shed some light on your discussion.
