Read this heart-wrenching story.
Really makes her boss seem like the bad guy, huh?
There's a common misunderstanding about jobs.
The job does not exist for the employee. The job exists for the employer.
The business has work that needs done that cannot be done as efficiently without an extra person.
In short, they needed Ms Rendon to show up for work. Businesses don't make exemplary employees sign paperwork warning them that their job might not be there when they get back. No business wants to be seen as Mr Scrooge; I am guessing that all manner of compassion was extended and a mile was taken where an inch was given.
I am guessing that Ms Rendon was absent a lot helping with a bad family situation.
I am guessing that her job performance suffered a great deal from the stress.
I am saying that Aviation Institute of Maintenance had a job that needed doing and she wasn't there to do it as agreed. Ms Rendon's failure to show up to do the job as agreed is not AIM's fault.
Because jobs are not for the employee, the business doesn't owe you one. Your salary and benefits are what they owe you; you exchange you skills and time for those.
