I worked at Time Out Sitters for my entire time at college and it was a great place to work. The owners are amazing and it was great making my own schedule. Their pay system was easy and it was fun taking care of kiddos all across San Antonio!
Cons
Not a super regular schedule, unless you find a regular client/family
Gives you independence and a flexible schedule to work when you can.
Cons
Last minute emergencies do not seem to matter to owners, such as family deaths or dangerous weather to drive in, you will get charged for a last minute cancellation to a babysitting job.
