The Protection of Employees (Part-Time Work) Act, 2001 provides that an employer cannot treat a part-time employee less favourably than a comparable full-time employee in respect of their conditions of employment. These conditions include including, pay, holidays, sick pay, pensions, access to jobs, promotion, training, etc.
However, the Act does allow for an employer to treat a part-time employee less favourably than a full-time employee if the reason for the different treatment is for the purpose of achieving a legitimate objective of the employer, andemployer and is not based solely on the part-time status of the employee.
