I worked at Lincoln for a year and it was one of the best working experiences I have had. The staff there are all great and the management do what they can to foster a real community spirit within the organisation. Targets are realistic and talked through and the commission structure is clear. As a business they genuinely seem to care about their staff as well as their client and candidates.
I left Lincoln because I wanted to try something outside of recruitment but would have no hesitation recommending them as a place to work.
