Dear John, How is going recently? Due to some unpleasant experience in work, I really want to share with you。 Mary has promoted me to trainee supervisor for half a year。on one hand, my payment hasn't changed, on the other hand, my workload has increased a lot。 Ann, who is my manager, possesses a very bad impression on me。 she always evaluate me with low working efficiency, thus forces me to overwork almost everyday! Till now, I didn't even pass the Middle EV。 God knows when would she promote me to the formal supervisor。 I am now in a paradox and confused。 John ,can you kindly do me a favor with some advice?Yours faithfully,Sam。
