I live in Keighley west yorkshire and work nearby near the border of Lancashire, I have been cleaning windows for about 30 yrs, and over the years had a good relationship with other window cleaners from my town and around the area, the problem is window cleaners coming over from Lancashire to work in the area I work, why? because they all seem to think that when they work in an area they own the place, I work streets that other cleaners work and vice versa with no problem, but these guys regardless of how long they have been cleaning an area are very agressive to other cleaners and customers who try to employ any one but them, has any one else had this kind of problem, how can it be dealt with (with out the use of violence) I'm interested to know.
