im going to file wrongful interferance with employment on a coworker, i dont know where shes stays so can i have her served at the job. im kinda sure

after 27 years and lots of medical issues (stage 3 cancer,diabetes,poppin my neck),i was terminated for using my phone (a picture) in the breakroom- where everyone does it. personally, xmas,holloween management has taken my pic before,etc.. a not involved lady later told management and they fired me, EEOC feels i was targeted and theyr investigating. im told after 3 weeks they hired her son. h r wont tell me what statement she made but my GDOL paperwork states-phone use in breakroom, i appealed for benefits and the company didnt show for hearing so i got benefits. i was fired feb 3. i was at 17.35 an hr so ima sue her for the max of 15000 since she wants to be in my and this other ladys biz. 2nd question- i had 5 weeks earned vacation- should i have gotten that when fired/ i see no rep agent for the woodbridge corp so should i sue the plant head for it, its alittle more than 3 grand that i earned in vacation time. i called but they wouldnt answer or return my calls
