Doing a 2 man's job but without proper compensation

I would just like to inquire if it's legal for a BPO company to assigned to an employee a 2 man's job without asking for agreement from the said employee and without proper compensation?

--I am currently working as a technical consultant with a program and as of the moment they wanted me to be train as a customer service/retention representative ---and later will be taking in calls both from the said splits --so basically I am going to be doing a 2 agents jobs but will not be getting additional compensation ---does the company have the legal right to make me comply?

hard situation. keep at it and you can be considered on a promotion track. complain, and that's a career killer.

talk to your supervisor and HR and try to get a proper agreement on what's to happen.

thanks for the reply!

Totally true --- embracing the change will get me have the job longer -- non-compliance will give them reason to kick me out of the company -- it's just too obvious though that they are cost cutting at the expense of their lowly employees ---sigh--

Ganito din yung situation namin ngayun atty.
Tech-support ako sa isang program tapos ni-re-require kami mg-training for customer service, pagkatapos nun ay ittrain din kame for retention. Eventually, yung calls na mare-rereceive namin sa isang araw ay halo-halo na. In other words, Hybrid-consultants. Yung dating sa aming mga apektado ay cost cutting, imbes na mag-hire sila ng additional na workforce for Customer Service and Retention, i-t-train na lang kami para lang makatipid, di naman po nagbabago yung sweldo namin. Meron po ba legal advise para dito?? or wala kami choice kung hindi sumunod na lang?

same advice as i gave above
