Would you recommend working at a call center in Manila if you're a single parent to a one-year-old?

Honestly, it depends on your current situation. If there's someone to look after you child, working at a call center or any other industry should be fine. Regardless of the industry, you would still be out of the house to work. The only difference is that, call centers still let you work even on holidays, so that's one thing that you may want to consider. Some companies also require you to work on weekends, so that's another thing. On the other hand, working at a call center could be less demanding when it comes to working hours (except when you are required to go OT), unlike with other industries where you are often times expected to stay beyond office hours or do field work/training in other locations.
