(2013) 10 SCC 324 for claiming the back wages, the workman is required to specifically plead in the pleadings qua the gainful employment and then onus is upon the management to prove. If the management is able to discharge, then the onus is again shifted on the workman to prove, otherwise the presumption has to be drawn in favour of the workman . In the absence of any pleadings or the evidence, the onus never shifted upon the management and therefore the workman failed to prove the fact of the period he was out of job / was not gainfully employed and thus, in my view the claim of the back wages has rightly been rejected. As regards the refund of Rs.1,50,000/- the contents of the bond attached to the petition filed by the workman would not reveal that in case amount is not deposited, ie., there was a negative condition o f forgoing the employment. No material has been placed before the labour court or this Court for deposit of the said amount. Accordingly, the labour court rightly rejected the said claim.
