walgreens being forced to resign or step down to service clark after working had for 10 years no reasion revere, Massachusetts

i have been working with walgreens company for ten years, and i have the best customer service in my store, working over night shift for 8 years 2 years day time .

when i was transfer to revere store for the second time the store manager gave me the overnight check list which is being given to all managers i did not have any problem with it and he started giving me an additional check list and was really too  had complete these those two because was to much but was doing it without even taking break in order to complete  it.

Towards the end of 2010 i was again given an assignment on addition to the two big check list and told me that i have to complete all the check lists plus checking the out dated the whole store,and i told him it is impossible because the store is gating so busy to take care of customers ringing ,stocking scan damages and to do all the check lists so he wrote me up.

In may this year he come and said the same thing i told at list to come over night and see how busy we are i have only one cashier both of us ring the register i do not take breaks at because i want to finish and i ask him to take some of the task off the over night like checking part of out to give to day time crew.

in july 2011 he come and told me to resign .
