I did it a lot years ago when DCs were younger. It supplemented other part-time income, worked with their school hours and suited me just fine. I needed to supplement my income as a single mother
I still do it now sometimes all these years later. Its a good way of saving up for a holiday, for instance. I don't intend to do a 9-5 ever again. This supplements my self-employment + the 16 hours p.w. work I do outside the home.
I got into it after reading an article in a women's magazine about it. Im not prudish at all and thought it would be easy money. It isn't...it can get to your mind talking smutty to mostly men all day, for instance....you feel burnt out. Then again on other days its fine. I just balance as necessary, I know when Im feeling up to it and when Im not.
But, I won't lie - when you can sit on the settee in your oldest pyjamas, hair in a mess, barely move a muscle, MN'ing or watching tv whilst waiting for calls, or you can't sleep one night and think eff it, if Im going to be up for a couple of hours I may as well take some calls - and make good money then do the same tomorrow - it really does motivate you to continue.
No, it isn't brilliant money but if you put in the time its a good earner + you don't have travel costs to think about
I didnt think about it too deeply, and I had short-term goals with it..ie, ok earn this today, that'll pay for haircut & treatment. Earn this tomorrow, thats the DCs school lunches covered, earn this amount per week during the 6 week summer hols so the DCs assault on your pockets won't feel so painful...!
I still don't quite believe it when I hear of women who do this full-time. I simply don't think you can, unless you are single no other responsibilities..you'd have to be near your 'phone all day, up for talking all day thinking up varied scenarios etc . My brain would sizzle.
But yeah, I could do 10 hours weekly, on a week I wasn't so much feeling to hear all the "phone talk". & on another week when I knew I needed more money to get stuff done could very easily do 30 hours..especially "graveyard shifts" when you earn more...you're working from home structuring your own hour so you work when everyone's in bed if you like
I know it wouldn't be for everybody and quite understand that. But it suits me 100%...its guys on the end of the phone (a few women call too) I cant see them, don't know them so I don't feel that involved. & itsnot always sex talk either
