Dh worked in a job from April 2011 advertised at 15 hours a week (although this was slightly more in the summer and less in the winter it averaged out) until October 2012 when he got an email the night before he was due in asking him to stand down for the winter ( we half expected this as the previous year he had had limited work) and they'd be in touch when they had work for him again. They were a bit unreliable to deal with and dh wasn't confident they'd be in touch but went with it.
Last week I saw the job advertised combined with another job. Dh assumed that the other man (P) had now left too. By coincidence dh bumped into P on Sunday and he hasn't left and wasn't aware that his/dh job was being advertised ( they won't need two of either post).
Dh is now chasing for a P45 as he obviously isn't going back and wasn't expecting anything else from them but I was interested in what should happen ( and for the other bloke who has been there about a year longer)
