Under rules in force until 1st October 2002 an employee whose contract of employment was for less than three months (or shorter specified period) did not have any "period of entitlement" and so was not entitled to statutory sick pay (SSCBA 1992, s.153(1) and Sched. 11, paras 1 and 2(b)). This rule was abolished with effect from 1st October 2002
In respect of an employee who has been continuously employed for three months or more under a contract "for a term certain of one month or less", normal employment law provisions deem his contract to be for "an indefinite period" (ERA 1996 s.86(4)).
