hes apparently 'working' now, will i see more cs?

[Butterfly Child]

(the title should say shouldn't i be seeing more cs?)

so xp txt me today saying he can't have dd on sunday now but will have her sat for the day( lucky i had no plans with her ) the reason being as he might have to work now..(i was like to myself, since when do you have a job) i havent said anything yet or asked about his 'job', if he is working, wouldnt it up my cs payments.. from the what $7.46 i get a week or not, unless hes getting paid cash in hand.. i mean where struggling as it is.. im not going to say anything i dont really want to start anything but i mean is this right ?

im not really familiar with the whole cs stuff. and to be honest i havent spent a dime i have gotten from him(for cs) ive put it in a savings account for her, but things are getting tighter financially and i wonder if he can really do this not to me but to his own daughter?
