Sir, if my work is pending then surely I do not have any problem in working at weekends. And about night shift is I am ready to work in nights but if company provide full security for girls during night times then working in night is not issue for me. I will be there in company any time if my presence require.
If the company needs my presence then I can sacrifice nights and even weekends.
Definitely there will be no problem working in nights and weekend if work demands my presence.
Otherwise I will be more happy to spend my nights and weekends with my family.
