My friend works in company having offices in various cities in India. He works in Mumbai office. His duties are mostly field duties - doing audits at clients place. As per his appointment letter his working days & time is as per location i.e. office where employee located . Some of company's offices in other cities have five & half days work week.Mumbai office works 5 days - Sat , Sun is off. Recently his boss is asking him to work on Saturdays also. They do not give comp off. They pay some negligible amount as allowance. Some of his colleauges & very few other employees work on Saturday.
As per company policy employees with five days work week have lesser leaves & paid holidays compared to five & half days work week.
Is it exploitation of employee. What can he do about it. Please advise.
