So glad to see this thread. I am in my 6th year in a tt position, and I got tenure at the end of my fourth year... I also thought I would be slacking off post-tenure, but it is quite the opposite.
I teach at a comprehensive university with a high teaching load, but I still have expectations for research/scholarship. We have 4 children, and DH works full-time also. All I can say is our lives are a big juggling act!!
Only in summer I have time to think about research, and I have had to move into an "easier" field so I can have some publications during this intensive child-rearing period. I have to balance the drive to stay professionally active with my much stronger desire to spend time with my kids since summer is when I can really catch up with their lives.
I wish there was some way to make it possible for women in academia to take time for child-rearing and still return to their careers. This will make it a lot easier to encourage young women to go into academia...
Still I believe most of us have really interesting fulfilling jobs!!
