the more I think about it, the less sure I am that it would work!
I usually work freelance from home, fitting it into school hours plus longer days with clients about twice a month. One of my regular clients has asked if I'd be interested in covering for her fulltime role while she is temporarily seconded elsewhere. The suggestion is two days per week in her office a good long commute each way then the rest from home.
Childcare plus railfare works out at (at least) £60. This isn't a particularly well-paid type of job, though freelance is better than employed rates. No one seems to know yet if this would be 'long-term freelance' or 'short-term employment'. But I have a feeling my cautious interest has been taken to mean 'problem solved, see you in September' (yes, it now turns out to be that sort of short notice). They are one of my best clients, and I don't want to piss them off. Aaarghh. Aaarggh, aarghh.
