70% of IBM managers oversee teams with at least one remote worker.

When you look at the sheer volume of perks this information technology company offers its working moms, it’s hard to believe women don’t fill every job here. New mothers can take three years off after the birth or adoption of a child with at least six weeks fully paid. Women who adopt are reimbursed for up to 80% of their related expenses, up to $2,500 per year. In addition to three on-site child-care centers, the company offers two thirds of its workers priority access at near-site childcare centers, plus resources and referrals to find any other type of care they need. If children have a mental or physical disability that health insurance won’t cover, parents can tap a dedicated financial fund to defray the cost of therapy and treatment. Also impressive: Employees’ college-bound kids are eligible for up to $12,000 in corporate scholarships.
