Is it alright to have to take time for bathroom breaks out of another break time?

I do not know that the employer is required to give you a separate bathroom break. You should use the bathroom when you are on break. If you have to ALSO go at another time, most employers understand, but they could discharge you for being out of your work area. It sounds like you are trying to make trouble by pushing for what you believe are your rights. If so, this is unlikely to help you in the long run. You could end up feeling like you won the battle, as you stand in the unemployed line.

Here is the rule: your employer must "make available", a 10 minute rest break for every 4 hours, or fraction thereof when you work. That means, sometimes you have to ask, can I go on my break, as if you don't ask, it could be use it or loose it. Rest breaks are on the clock. Meal breaks, unlike rest breaks, are off the clock. to these are your only 2 different types of breaks. the meal break would be made available if your shift is greater than 6 hours, and it should be taken at the 5 hour mark.
