The tribunal sitting last week found that Salat was unfairly dismissed, and awarded him 12 months' wages in addition to his other losses.
Salat had also been assisting construction union UCATT with organising and translating on behalf of site workers who had been brought in from India to work on the temple.
UCATT London official Michael Dooley said Salat, who is a British citizen, had suffered simply because he asked for a contract of employment.
Two years ago Shrico was at the centre of a row after being accused of bringing workers from the Indian subcontinent and paying them 30p per hour. The workers eventually received back pay of £100,000.
