I believe Care.com should have a better open communication with the care providers and make sure they're not being taken advantage of.
It depends on the job and the department. Every role at Care.com is different. You have a lot of jobs that are remote and then you have jobs at different locations through-out the country and world.
Overall, it is a conservative corporate environment with a start-up feel. Everyone is friendly and there is no real dress code - however most people dress business to business casual depending on the role. Part-timers are expected to work around 30 hours and full-time around 60.
