I know there have been questions posted here along these lines in the past, but I would be interested in current opinion on this issue.  

We have a part-time employee who has requested two periods of unpaid leave over the next calendar year so that she can go travelling.  We are happy to grant her these periods of unpaid leave, the question is, will she continue to accrue holiday leave entitlement during this period of absence?  

My research into this area has drawn up conflicting opinions and conflicts in the absence policies of various public sector departments, with some stating no holiday leave accrues during unpaid leave and others listing unpaid leave along with maternity and sickness so holiday leave accruing.
