As per the provisions of the Industrial Disputes Act, 1947, which one of the following is not included in the term 'wages' ?

According to Section 2(rr) of the Industrial Disputes Act, 1947, the term 'wages' means all remuneration capable of being expressed in terms of money and includes components like dearness allowance, the value of any house accommodation (or supply of light, water, medical attendance), and any travelling concession.

However, the section explicitly excludes the following from the definition of 'wages':

• (a) Any bonus;
• (b) Any contribution paid or payable by the employer to any pension fund or provident fund;
• (c) Any gratuity payable on the termination of service.

While the Act includes 'travelling concession' and general 'allowances', 'bonus' is a statutory exclusion under the definition provided in the Industrial Disputes Act. This distinguishes it from other labor laws like the Payment of Wages Act, where travelling allowance is also excluded.
