How do you really assess an employer’s family friendliness? Look to the subtleties. Lisa Levey, a Boston work/family consultant says you should determine:
If employees you encounter talk about non-work subjects.

If higher-ups in the company take advantage of work/life programs.
If the atmosphere seems relaxed and flexible, as opposed to everyone crowding in the door at 9 a.m.

How many employees take advantage of different workstyle options, such as job sharing, part-time schedules and telecommuting. If you can talk to other employees in the department.

Why the person before you left.
What the stress level and time expectations are.
