Flatmate refuses to take the bin out

Yeah, it's only a warden. But advising someone to ignore the obvious framework in place to deal with this sort of thing and encouraging them instead to engage in personal conflict, thereby potentially falling foul of that framework herself as well as inflaming the situation in the flat, is just irresponsible and myopic. Sorry.

In my opinion the situation needs to be 'inflamed' to prove a point... im not sure why you are rambling on about 'framework'??

Get up stand up, get up for your rights'

You're right. OP, take this person's wise, constructive advice.
