Thank you very much Sir for your prompt reply.
Actually, this step is taken after considering the few experiences the Company had, wherein after giving proper training and also incurring cost on their medical check-up, uniforms, transportation and such other cost, the employees before their probation period either resigns or abscond; and the Company is left out with nothing but to again put additional time and cost to look for other candidate.
I am not sure whether this will be an effective step, but we should have some reliefs from such act of the unprofessional employees.
