hmm, I see where you're coming from however in my (limited) experience agencies toe the line of legality, whilst leaning heavily over it.
I personally have had similar things happen to me; I've taken a legitimate sick day and then been told that the shortage I was making up for has been filled, or some such blah. I've also been held in limbo situations, not knowing each day whether I would be needed or not, waking at 5am and getting ready incase I got a phonecall asking me to make it in for the start of shift... or not.
I'm not saying these experiences legitimise a clearly unbalanced and unfair relationship (though to put it in perspective; atleast its not a victorian workhouse), alls I remember is that citizens advice were unable to help me.
I think you need to be working for two years before you can be considered an "employee" with full blown rights. Anything up to that is more subject to any agreements you've made i.e. the fine print of contracts, job descriptions, the wording of the positions offered.
