Recently there was a question on the Autocat electronic discussion list on classifying the title Drafting employment contracts by Gillian Howard with the main subject heading of Labor contract – Great Britain. Her item included model clauses, draft letters and contracts, part-time work, fixed-term contracts and changing terms and conditions. Similar works are classed in two different numbers: KD1634: Law of England and Wales--Contracts--Particular contracts—Contract of service. Master and servant, and KD3096: Law of England and Wales--Social legislation--Labor law—Labor standards--Employment and dismissal. The cataloger asking the question liked KD1634 more than KD3096 because it is under contracts – however she noted that she was confused about what master and servant meant.
