specimen copy enclosed in additional typed set of papers, dated 19.5.2016, which pertains to one of the workmen, namely, Thiru.S.Venkatesan, on the same terms and conditions and such employment shall be continued in respect of other petitioners who were offered such appointment till they attain the age of superannuation. As rightly contended by the learned counsel for the respondents 2 and 3 that the requirement of man power may change from time to time due to fluctuating market trends as the ground handling activity may increase or decrease depending upon the client-Airlines patronage. Therefore, considering the said submissions, this Court is of the view that as long as man power requirement is there by the second respondent, the services of the petitioners ought to be utilized and the petitioners at no point of time should be replaced by any other casual arrangement by resorting to employ other persons. It is made clear that on the basis of genuine man power requirement, it is always open to the 7th respondent to downsize or rightsize the employment as and when the situation demands and depending on such contingencies, these petitioners shall be continued in service with the terms and conditions of services as stipulated by the 7th respondent. In any case, the petitioners' employment cannot be brought to end by adopting any unfair mean or unfair labour practice by bringing other casual workers from the open market in order to displace the petitioners herein.
