You now get paid $13.92.
New job would pay you $13-14/hour. That is basically very similar to what you have now.
New job: No vacation until 1 year after. No paid sick days. 4 day work week at 10 hours per day. $200 for medical and you pay the rest. (so your paycheck will be eaten up by the cost of your medical insurance each pay check). So you may not be making more money at this new job.
Present Job: you can get off whenever you need to, you get sick days and per your child needs, you get paid $13.92, you have off whenever school is closed (that is more than you would get per the new job and you only get 1 week vacation AFTER being employed with them for 1 year), your current job is located only 1 block away from home, gas costs are less too.
You feel stuck in a rut: to me, you have to figure out IF... you feel stuck in a rut because of your job.... or just due to your personal life and personal reasons. IS your feeling stuck in a rut because of your job... or just because you feel bored and perhaps, can find some Hobby or other interests to do as a Mom?
New Job: Advancement would be contingent on IF.... you go to school to be a CMA. And they would then pay for schooling. Are they going to pay for it 100% or just a portion of the costs of schooling and you have to pay the rest???? (2) Do you even want to go to school and know what that will entail in terms of time spent studying, time spent at home and with your child, and can you afford to go to school? In terms of costs and in terms of the amount of time you would be home or not, due to school responsibilities??? And... will the new job pay for your school books AND supplies too? School books and supplies costs a lot as well. This is another cost.
You said you need more money and so have been job searching... but, the new job... is paying about the same as your current job... plus you'd be working 10 hour days 4 days a week and spending more in terms of gas and per your medical insurance costs.
So, would you even be making "more"... at this new job???
Your paycheck will be eaten up by medical insurance costs and gas costs and you get NO vacation for the 1st year. And no sick days. So if you are sick and/or your child is.... you will not be paid and have to pay for childcare if/when your child is sick and has to stay home.
